PROAIR: Active protection of multi-material assemblies for aircrafts

Svet On Galvanic Couples

The main objective of this project is the development of basic strategies for active corrosion protection of multi-material assemblies in new “green aircraft” designs. In this way the project is driven by a strong industrial demand but has at the same time a very important research component on a fundamental scientific level. An essential starting point is a detailed investigation of the reaction mechanisms of corrosion caused by galvanic coupling effects in different multi-material combinations including Carbon Fiber Reinforced Plastics (CFRP) and metallic materials. This knowledge will be used as a basis for simulation of the localised corrosion processes in critical zones such as micro-confined hybrid joint areas and defects in coatings for multi-material application.

Another significant innovation is expected in the area of synergistic corrosion inhibition for galvanically coupled metals or the cases when a metallic material is connected to CFRP. The new active corrosion protection solutions based on novel corrosion inhibitors or their synergistic mixtures for multi-material combinations also present an important novelty (Fig. 1).

Synergetic Complementary Proair

Figure 2. Synergistic complementarity between the research lines in PROAIR project.

The development of such new approaches is only possible via deep mechanistic investigation of the degradation processes in confined environments formed at multi-material joints. The second essential stage is finding the synergistic inhibiting combinations which can provide effective suppression of corrosion processes in the case of galvanically coupled dissimilar materials. The ultimate step is introduction of inhibiting compounds to the protective layers, adhesives and sealants used in multi-material design of aircrafts.

The project also aims in creation of stimulating and interdisciplinary R&D and training partnership, with actors from the academia and private sector, promoting the exchange of ideas, methods, techniques as well as enabling an accelerated technology transfer from science to industrial scale and of course a continuous collaborations between the stakeholders. The topic demands strongly innovation and interdisciplinary skills, since there is a lot of pressure from the private sector to develop more sustainable solutions for light-weight design of “green aircrafts”.

LORCENIS - Long Lasting Reinforced Concrete for Energy Infrastructure under Severe Operating Conditions

Advanced Engineering Software Tool

Advanced Engineering Software Tool

The main goal of the LORCENIS project is to develop long reinforced concrete for energy infrastructures with lifetime extended up to a 100% under extreme operating conditions. Four scenarios of severe operating conditions are considered:
1. Concrete infrastructure in deep sea, arctic and subarctic zones: Offshore windmills, gravity based structures, bridge piles and harbours
2. Concrete and mortar under mechanical fatigue in offshore windmills and sea structures
3. Concrete structures in concentrated solar power plants exposed to high temperature thermal fatigue
4. Concrete cooling towers subjected to acid attack
The goal will be realized through the development of multifunctional strategies integrated in concrete formulations and advanced stable bulk concretes from optimized binder technologies. A multi-scale show case will be realized towards service-life prediction of reinforced concretes in extreme environments to link several model approaches and launch innovation for new software tools. The durability of sustainable advanced reinforced concrete structures developed will be proven and validated within LORCENIS under severe operating conditions , starting from a proof of concept (TRL 3) to technology validation (TRL 5).
LORCENIS is a well-balanced consortium of multidisciplinary experts from 9 universities and research institutes and 7 industries, including two SMEs, from 8 countries. All partners will contribute to training by exchange of personnel and joint actions with other European projects and will increase the competitiveness and sustainability of European industry by bringing innovative materials and new methods closer to the markedt and permitting the establishment of energy infrastructures in areas with harsh climate and environmental conditions at acceptable costs.
WZK will lead the work package entitled “Advanced software for modelling and end-of-life prediction”.

MULTISURF - MULTI-functional metallic SURFaces via active Layered Double Hydroxide treatments

SEM images of the bare AA2024

SEM images of the bare AA2024

The main objective of the proposal is development of active multi-functional surfaces with high level of self-healing ability on the basis of Layered Double Hydroxide (LDH) structures. The innovative active treatments are planned to be applied on wide range of metallic substrates relevant for transportation industrially. The main targeted functionalities of the created surfaces are related primarily to enhanced fault tolerance and active protection against contamination, biofouling and corrosive damage. The active functionalities will be introduced via incorporation of functional molecules within LDH structures grown directly on the metallic surfaces in result of a conversion process (Figure 1).

Possible mechanism of triggered release from LDH structures

Possible mechanism of triggered release from LDH structures

The activation of the desired functionality on demand will be achieved utilising intrinsic “smart” release properties of LDHs under various external triggers (Figure 2). An additional surface “health monitoring” functionality will be introduced based on the same principles or using LDH structures as sensing nanoreactors.

The project also aims in creation of stimulating and interdisciplinary R&D and training partnership, with participants from the academia and private sector, promoting the exchange of ideas, methods, techniques as well as enabling an accelerated technology transfer from science to industrial scale and of course a continuous collaborations between the stakeholders. The topic demands strongly innovation and interdisciplinary skills, since there is a lot of pressure from the private sector to develop more sustainable solutions for light-weight transportation solutions. The developed treatments must be compliant with environmental regulations, must present reduced thickness/weight, and must promote energy saves, with longer lifetime (Figure 3). Moreover it has to be considered that the related processing and assembly steps have to be economically competitive. Thus, the actual times are very challenging for this field and new skills and trained people are an acknowledged need.
MULTISURF project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 645676.

SARCOS COST Action - Self-healing As preventive Repair of COncrete Structures

The search for smart self-healing materials and preventive repair methods is justified by the increasing sustainability and safety requirements of structures. The appearance of small cracks in concrete is unavoidable, not necessarily causing a risk of collapse for the structure, but certainly accelerating its degradation and diminishing the service life and sustainability of constructions. That loss of performance and functionality promote an increasing investment on maintenance and/or intensive repair/strengthening works. The critical nature of such requirements is signified by their inclusion as priority challenges in the European Research Program.
The first focus of this proposal is to compare the use of self-healing capabilities of concrete with the use of external healing methods for repairing existing concrete elements. Despite the promising potential of the developed healing technologies, they will be real competitive alternatives only when sound and comparative characterization techniques for performance verification are developed, being this SARCOS’s second focus. The third focus deals with modelling the healing mechanisms taking place for the different designs and with predicting the service life increase achieved by these methods.
SARCOS COST Action will be leaded by research institutions searching on different self-healing technologies and repair solutions for extending service life of new and existing concrete structures, with high expertise in developing characterization techniques. Also specialists on modelling healing mechanisms and experts on numerical service life prediction models contribute for the Action’s success. This composition provides a solid framework to advance in implementing innovative and sustainable solutions for extending the service life of concrete structures.

SMARCOAT - Development of smart nano and microcapsulated sensing coatings for improving of material durability/performance

Detection of corrosion processes using polymeric capsules with pH indicator

Detection of corrosion processes using polymeric capsules with pH indicator

The project aims to develop an innovative approach to impart sensing functionality and detect substrate degradation. The degradation processes targeted will be corrosion of metallic substrates and mechanical damage by impact on fibre reinforced plastics and composites (FRP), used as structural components in the vehicle industry worldwide. The innovative sensing materials are based on controlled release of active species, encapsulated in polymeric and inorganic capsules with sizes ranging from several micrometres down to the nanometre range. These will be designed and prepared in a way that responds to specific triggers associated with the nature of the degradation process. The functional materials will be subsequently incorporated as additives in organic and hybrid organic-inorganic coating
matrices, or directly impregnated in the substrate (FRP). The goal is to get coatings capable of sensing substrate degradation at early stages, making maintenance operations cost-effective without jeopardizing safety. The range of selected materials encloses systems conceptually designed to be prepared and tested for the first time at lab scale (high breakthrough at research level) and others already studied at lab scale with promising results and which can already be tested at pilot scale (high innovation level). Furthermore, the characterization encompasses lab-scale, cutting-edge technologies and modelling, as well as upscaling and industrial validation. The consortium has strong knowledge and relevant experience from previously conducted projects on the topic. The project foresees intensive exchange of staff between the involved partners, which are from both the academic and non-academic sector. Also, staff exchange with a partner organization outside the EU is planned.

TUMOCS - TUneable Multiferroics based on oxygen OCtahedral Structures

Cation ordering in octahedral layers of LDH for M(II)/M(III) = 2:1 (top) and 3:1 (bottom)

Cation ordering in octahedral layers of LDH for M(II)/M(III) = 2:1 (top) and 3:1 (bottom)

The main objective of the project is development of new lead-free multiferroic materials for prospective application in forms of films and/or arranged layers in which the cross-coupling (magnetic-dipolar-elastic) can be tuned by both internal and external factors. This objective is to be achieved through preparation, investigation, and optimization of two kinds of Bi-containing oxygenoctahedral (BCOO) systems with paramagnetic ions involved: metastable perovskites and layered double hydroxides (LDHs, Figure 1). The characteristic feature of such materials is a possibility of supplementary control parameters in addition to temperature and external electric/magnetic field.

Two possible antipolar subgroups for the asprepared BiFe0.5Sc0.5O3 sample with the Pnma symmetry

Two possible antipolar subgroups for the asprepared BiFe0.5Sc0.5O3 sample with the Pnma symmetry

Polarization in such metastable perovskites is easily switched by application of external pressure (or stress in the case of films) (Figure 2). Electric and magnetic characteristics of BCOO LDHs are tuned through appropriate anion exchanges. It makes these characteristics dependent on environment conditions: humidity, pH, and presence of specific anion species. The BCOO materials of both mentioned groups are of interest as new and unusual multiferroics. No LDH materials have been considered as potential multiferroics so far, while the metastable BCOO materials proposed in this project have not been obtained before. Besides, a tuneability and high sensibility of their properties to external impacts make them promising for applications in sensors. Exploration and development of such materials require consolidation of specialists of complementary expertise in Physics, Chemistry, and Materials Science, with access to and skills in using specific and unique equipment and facilities. Therefore, formation of an interdisciplinary network of teams with different scientific culture and ensuring the effective knowledge & expertise transfer is important objective of the project. Advance in development of the BCOO multiferroics has potential market opportunities for R&D SME involved in this project.

FACTOR LuFo - Future Advanced Composite Bonding and Bonded Repair

FACTOR_LuFo

Factor-Hereon focusses on the electrochemical properties and its impact on the bonding performance of Ti based engineering components in aircrafts. In order to have a deeper understanding of failure mechanism and, therefore, set up the most efficient Ti-joint design and related processing / pretreatment, it is necessary to perform a detailed study regarding the properties of the native oxide films on titanium as well as the titanium films after anodizing (including intermediate steps in the process). Based on the project outcome, an optimized surface finishing via technical N4 processing (Airbus) will be designed. If quantified data on the film feedback are available, the engineering and construction chain can be adjusted, towards minimal risks of failure of e.g. Ti-CFRP structural bonds.

ALMAGIC - Aluminium and Magnesium Alloys Green Innovative Coatings / Clean Sky 2

With the use of light alloys, such as aluminium and magnesium, new applications have been found to quickly improve existing designs in the aircraft industry. The disadvantage of using these materials is that they are particularly susceptible to corrosion. Environmental degradation is a limiting factor for magnesium–aluminium (Mg–Al) alloys in outdoor applications. An effective way to protect alloys from fast degradation or reduce to the degradation rate is surface treatment. Hexavalent chromium has served as the primary means of corrosion protection in the aircraft industry since 1936 and allowed for the distinctive bare-metal finishes of the World War II era. Hexavalent chromium is a known carcinogen, with the major route of exposure through inhalation of vapour or dust. The chromates are among the current chemicals for which industrial users must find substitutes, or request authorisation from EU regulators to continue their use. In the case of chromium trioxide and the acids, the application deadline was March 2016 and the “sunset” date for the substances is September 2017. Therefore, there is an urgent need facing the aerospace industry to replace the conventional corrosion inhibitor, hexavalent chromium. Regulatory and market drivers are motivating a global effort in the aerospace industry to replace hexavalent chromium-containing materials with hexavalent chromium-free alternatives for various applications.
The ALMAGIC project is focused on solving the aforementioned problematic by validating the developed innovative alternatives to chromium (VI) coatings for aluminium and magnesium alloys. ALMAGIC will ensure the developed solutions comply with the REACH regulations, while all quality standards are met. The project is co-funded by the Clean Sky 2 Joint Technology Initiative (CS2 JTI) which is a Public-Private Partnership between the European Commission and industry.

TRANSFERR - Transition metal oxides with metastable phases: a way towards superior ferroic properties


triple_phase_state_one_layer

Fig. 1 : HRTEM image of the Bi1-xPrxFeO3 at the phase boundary. The regions with different structural symmetry are marked by dot lines. Insets show FFT images of the different structural phases.

The main objective of the project is development of complex transition metal oxides with perovskite-like structure having improved and controllable (multi)ferroic properties. The mentioned materials are manganites and ferrites with optimal composition having distinct magnetization, polarization, (magneto)transport properties and/or magnetoelectric coupling. The idea of the project is to utilize reduced structural stability of these oxides governed by multiple structural state (Fig. 1) which increases their sensitivity to external stimuli.

TransFerr_WZK

Fig. 2: The XRD pattern of the Pr-doped BiFeO3 compound with composition near the phase boundary. The inset shows an evolution of the structural peaks attributed to the different structural phases

Improved functional properties of these oxides can be controlled via modification of the chemical bond character, structural parameters, stoichiometry, defects etc. The reduced stability is associated with the metastable structural state formed in the vicinity of the phase boundaries, while this state presumably consists of coexistent nanoscale regions of the adjacent structural phases (Fig. 2).
The Project realization is based on the two main scientific approaches aimed at the creation of metastable state of the compounds: the first one considers a design of ceramics via chemical substitution and post-synthesis treatment by high pressure and/or thermal cycling in gases to induce nanoscale regions, the second one assumes chemical routes synthesis of the films and ceramics.

Besides the fundamental interest of the Project associated with the phase transitions and related phenomena affecting properties of the oxides the scientific teams consider the compounds under study to be effective materials for electronic applications (as magnetic/electric field sensors, magnetic memory elements, filters etc). Research of these materials requires consolidative efforts of specialists in different scientific areas - Materials Science, Theoretical Physics, Solid State Physics etc. as well as an access to unique equipment and facilities. Another important objective of the Project is a formation of interdisciplinary network of teams and specialists with different scientific backgrounds which will ensure effective transfer of actual knowledge and skills. Development of the transition metal oxides with controllable properties has promising commercial opportunities for the involved commercial company.

FUMAS - Function integrated light weight construction of magnesium in car seat structures


Partners:
- Faurecia Autositze GmbH
- KODA Stanz- und Biegetechnik GmbH
- Deutsches Zentrum für Luft und Raumfahrt (DLR)
- JUBO Technologies GmbH
- TWI GmbH

The main aim of this by the Ministry for Economic Affairs and Energy (BMWi) funded project is using lightweight constructions in order to decrease the energy consumption of vehicles and thus to conserve resources and to reduce climate-damaging emissions. The benefit of the vehicles weight reduction like reduced energy consumption is independent from the engine, which is also ecologically worthwhile for vehicles with alternative engines. The work of this project is concentrated on the weight reduction of a car seat structure using a magnesium component in the seat back. Car seats are the mechanically most loaded components in the car interior and have a significant impact on the vehicle´s weight. At the moment magnesium seat components are implemented as die cast parts for small series. The potential of weight reduction of these parts is 30 to 40 % in comparison to steel. Furthermore, wrought magnesium alloys have better mechanical properties and a better formability than cast parts. A simple substitution of steel sheets by magnesium sheets fails on the one hand on the lower strength of magnesium sheets and on the other hand on the lack of suitable joining and corrosion protection solutions. An alternative process route which combines extrusion and warm forming can be the solution to be competitive to steel components. The options in the design of extruded profiles make it possible to integrate supporting and mounting structures which are not used in conventional sheet metal applications yet. The project FUMAS opens the opportunity to bring mechanically high loaded magnesium seat components in high volume industrial application by using this new production process and the realization of new design concepts.

Humboldt Research Fellowships - Expedient screening of corrosion inhibitors for Mg alloys


Humbolt_Project_Lamaka

The project specifically addresses the high susceptibility of magnesium alloys to atmospheric and galvanic corrosion. A light material, so attractive to automotive and aerospace applications, yet highly susceptible to corrosion is in focus of this research work. The research objective is to identify chemical compounds that effectively inhibit corrosion of magnesium alloys. A systematic search for inhibitors of magnesium corrosion is being undertaken as opposed to the isolated data reported before. Selection from the large pool of potential candidates was based on recently discovered mechanism of detrimental effect of Fe impurities on corrosion of magnesium. Compliance of identified inhibitors with current environmental regulations is verified in a thorough study of EU regulations. The project contributes to reach beyond current developments and establish European leadership in the emerging field of inhibitors of magnesium corrosion.

Marie Curie Individual Fellowship: MAGPLANT - Localized Corrosion Studies for Magnesium Implant Devices

MAGPLANT_Project

The goal of MAGPLANT is to investigate localized corrosion processes on magnesium and magnesium alloys, in biologically relevant environments. As consequence of knowing “what happens” microscopically at the interface between Mg-alloys and biological media, a large improvement is expected on the future fabrication of these structures.
The project will develop in various stages contemplating multidisciplinary research topics. The first stage will embrace the development of microsensors that can be effectively used for local measurements on the near-surface of Mg-alloys, such as pH and H2 sensors. Localized corrosion techniques such as SVET and SIET will used during the following stages, where selected Mg-alloys will be studied in bio-simulated media of increasing complexity in order to build sustained and progressive knowledge. According to the essence and core objectives of Marie Curie Actions, these findings will be disseminated in multiple information channels in order to engage with different societal sectors and collect increasing attention from policy makers and relevant technological partners.
As main scientific outcome of this project it is expected that localized corrosion processes on magnesium become thoroughly understood. This will help to control the corrosion rate of the metal and its alloys, which are currently the main barrier to their widespread application in biotechnology and other fields. As load-bearing implants, magnesium alloys will comprise adjustable biodegradability, high biocompatibility and above all, increasingly fast and effective healing periods, which can produce remarkable socio-economic benefits for injured patients, while establishing Mg-based prosthetic devices as the optimal and safest solution for load- bearing implants.

FUNCOAT - Development and design of novel multifunctional PEO coatings

Funcoat Wolfgang-dietzel

The main objective of the project is the development of multi-purpose, multi-functional surfaces via environmentally friendly plasma electrolytic oxidation (PEO) treatments. With a novel approach, the weakness of the PEO process (the inherent porosity due to the discharges forming the coating is often responsible for poor properties) is used to functionalize the coating using the open pore structure as a reservoir for nanocontainers or to bring particles with certain functionalities deep into the coatings (fast pathways). The main targeted functionalities are enhanced fault tolerance and active protection against corrosive damage as well as improved tribological behavior. Moreover, to extend this typical field of applications of PEO treatments and address additional industries and aspects, a set of less common functionalities, such as photocatalytic, magnetic, thermo- and electro-conductivity will be added. This is challenging and goes far beyond the state-of-the-art introduction via post-treatments. To deal with such sensitive materials, changes in the power supply are required and this is addressed as one of the key points of the project as well.

The essential key of the project is the formation and development of an interdisciplinary R&D partnership, where participants from both academia (five) and private sector (four SME) in four EU Member States or Associated Countries and in one Third Country participate, promoting and sharing their ideas, expertise, techniques and methods to solve this demanding challenge. This partnership will be beneficial for all participants, since new PEO hardware, environmentally friendly processes and applications important for industry
are developed, evaluated and promoted by the research institutions via presentations and publications of the obtained results. Laboratory based training and intersectional transfer of knowledge are key aspects of the FUNCOAT project, and the partnership gathers the topmost competences to carry out the suggested research program.

Hereon acts as the project coordinator and leads the work packages ‘PEO modification for transport application’, ‘Coordination and management’, and ‘Ethics requirements’.

FUNCOAT project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No 823942.

The present project approaches this issue from the side of synergistic inhibition integrated in protective coatings applied onto the metal substrates. The main idea is to find the environmental friendly synergistic inhibitive combinations which can provide effective suppression of corrosion of light metals (also for galvanically coupled dissimilar joints). Controlled release of inhibitors is obtained by loading them into appropriate nanocontainers. However, the essential step is the introduction of inhibiting compounds into the protective layers based on an multi-layer concept consisting of PEO coating for promoting adhesion and providing macro-containers, additional or integrated primer layers and final polymer top coats. This approach is used because the loss of nanocontainers to the environment should be minimized thus the containers are added into the open pores of PEO coatings creating a "container in container" solution (Fig. 1).
The achievement of these goals is not possible without extensive support of multi-scale modelling approaches on different stages of development process from inhibitor selection to the final design of the protective system and testing of the release of the inhibitors from the coatings and its impact on environment and health. Molecular modelling approaches will be utilized in the case of inhibitor interaction with metallic, inorganic (PEO macro-container) or polymer interfaces (sealing top coats) and selection of environmental friendly inhibitors.
ACTICOAT project is financed by Federal Ministry of Education and Research (BMBF) in frame of Era.Net RUS Plus Call 2017.

Active corrosion protection of magnesium alloy via plasma electrolytic oxidation (PEO) coatings

Plasma electrolytic oxidation (PEO) is an advanced anodizing process which leads to formation of ceramic-like oxide coatings on the surface of light metals. The oxide layers developed by PEO are usually hard, strongly-adherent to the substrate and confer both corrosion and wear resistance. In spite of many advantages, the layers are generally composed of high porosity as a result of discharge breakdowns and gas evolution during the coating growth process. Moreover, the size of the pores increases with the coating thickness in many cases. Such an intrinsic porosity often compromises and even deteriorates the barrier properties of the layer. From another hand, the high porosity could be advantageous and considered as natural reservoir to load inhibitor-containing nanocontainers, which release inhibitors on demand. Recently it was shown that layered double hydroxides (LDHs) can act as such nanocontainers, releasing suitable corrosion inhibitors in the presence of Cl- or OH- anions. The general formula of the most common LDHs can be represented as [MII1-xMIIIx(OH)2]x+(Ay-)x/y·zH2O. Following their structure, the protective LDH action can be explained via the anion-exchange reaction induced by mentioned triggers. In other words, when corrosion conditions occur, the LDH nanocontainers release inhibiting anions and absorb corrosion-active ions such as Cl-.
Moreover, formation of LDH based nanocontainers in the pores of PEO layer will improve the barrier properties of the resulting system via sealing. In spite of significant recent progress, achieved in LDH formation on PEO treated Mg substrates. Two main drawbacks, limiting their further industrial applications, remain: (1) LDH formation occurs under autoclave conditions, (2) LDH are formed in the presence of carbonate anions, leading to the formation “dead” non-functionalizable LDH, which cannot be loaded with corrosion inhibitors. In the present study, we will focus not only on incorporation of inhibitor-loaded nanocontainers (both in- and ex-situ) into PEO coatings but also on direct formation of LDH on PEO treated surfaces in order to provide a controlled and prolonged release of the functional species to achieve active long-lasting corrosion protection for Mg alloys.

SeaMag "High-performance seawater batteries for marine application"

Seamag Summary Results

The aim is to develop high capacity and cost efficient magnesium (Mg) based seawater batteries with increased environmental compatibility suitable for long term operation of marine observatories. The partners plan to improve the performance of Mg-seawater batteries in different hydrodynamic conditions by finding the optimum combination of anode material, electrolyte additives and cathode design to achieve longevity of minimum 5 years and a capacity of 25kWh. Aqueous primary Mg batteries have several advantages for marine applications as they can operate at any pressure, have greater power storage capacities and are cheaper than lithium-ion batteries. Furthermore, since the unlimited supply of seawater serves as the electrolyte, the size and weight of the battery system can be considerably reduced. Possibly applications are autonomous subsea observation systems in the oil & gas and aquaculture industry.

SeaMag is funded by the MarTERA partners Research Council of Norway (RCN), German Federal Ministry for Economic Affairs and Energy (BMWi) and National Academy of Sciences of Belarus (NASB) and co-funded by the European Union.
