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).

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”.

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).

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.

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.

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.

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.
