Making Europe the first climate-neutral continent is the objective of the European action plan for the circular economy presented in 2020. One of the major axes is the improvement of the durability of products. However, localized aqueous corrosion is a form of critical damage because it is particularly insidious, insofar as it degrades the use properties of materials on a very local scale. It affects the durability of commonly used products and the safety of the most complex industrial structures. As such, integrating the issue of the resistance to localized aqueous corrosion of materials from the design phase, in other words working to design materials resistant to localized aqueous corrosion, is essential today. This chair project aims to develop research on the identification of microstructures resistant to aqueous corrosion to guide national and European industries in the choice and definition of processes for the development and implementation of sustainable materials.With regard to the CNRS' priority orientations, this project is part of the organization's 2019-2023 objectives and performance contract, in the "engineering" theme and in the context of the societal challenges "climate change" and "energetic transition".
Stratégie du laboratoire d'accueil
The four targeted laboratories (in alphabetical order: CIRIMAT, IJL, IRCP, LRS) have recognized teams in the field of aqueous corrosion. For each of them, the staff on this theme is limited and must be reinforced in order to be able to grow and allow France's visibility at the international level in this area.
The scientific community active in understanding the elementary processes involved in localized corrosion is currently sub-critical in order to respond quickly to the urgency of the major societal challenges represented by saving resources, lowering energy costs and environmental impacts related to the use of metallic structural materials. While the need for specialists is felt in many fields (for example in the field of stress corrosion of the emergency cooling circuits of certain pressurized water nuclear power plants) relating to corrosion, the community capable of apprehending these questions has in fact been on the decline in terms of staff numbers for several years. Regaining strength and increasing skills in this area requires not only appropriate training in universities, but also the recruitment of talented scientists who are already trained and experienced in this exercise. Recruiting a talented young researcher trained abroad in countries that have been able to maintain this type of activity, such as Germany or certain Anglo-Saxon countries, appears to be facilitated by the CPJ system, which is attractive and will allow the winner to be supported in an appropriate way to start their project.

Résumé du projet scientifique
Bringing to the highest level the understanding of the mechanisms of localized aqueous corrosion affecting metallic materials to allow the definition of microstructures resistant to this form of damage constitutes a scientific challenge that it is urgent to take up. The problem integrates the understanding of the different stages of the localized corrosion processes (incubation, initiation and propagation of the defect), and can be approached from the angle of the processes affecting the surfaces (passivation, native oxide film growth and rupture of these films) and/or conduct by investigating the elementary mechanisms of a chemical, electrochemical, physical and mechanical nature, and their interactions, leading to the propagation of the corrosion defect. The deployment of this approach will require taking into account the heterogeneity of real microstructures, and, in fact, the different relevant scales of analysis. It will also be a question of considering the conditions of use of the parts in all the diversity of real situations, taking into account the coupled actions of physico-chemical parameters characteristic of the aqueous medium and the mechanical stresses. The scientific contribution may be experimental and/or partly stem from modeling, via the analysis of the elementary mechanisms themselves and/or the development of dedicated tools.
Résumé du projet d'enseignement
The research theme of this CNRS chair may be declined in the various universities targeted on the territory according to the place of recruitment. The laureate could in particular contribute to teaching in materials science, electrochemistry, corrosion, etc. at the bachelor's or master's level
- Total financé (dont package ANR) : 200 k€
- Total du projet : 200 k€
The dissemination of the results will be done through world-class scientific productions: publications, patents, software... In addition, the results will be communicated to various targets such as scientific communities, media, decision makers, general public, schools, etc., with an adapted calendar. Specific tools may be developed such as websites, newsletters, meetings, international symposia, summer schools and conferences.
The CNRS is developing a strong policy in favor of open science. Open science consists of making research results "as accessible as possible and closed as necessary". As such, the CNRS aims to make 100% of the texts of publications resulting from the work of its laboratories accessible, in particular through deposit in HAL. The data produced must also be made available and reusable, except for specific restrictions. In addition, the guiding principles of individual evaluation have been revised in accordance with the DORA declaration, to be more qualitative and to take into account all facets of the researcher's profession.
Science et société
The relationship between science and society is now recognized as a full dimension of scientific activity. The project will develop this dimension in synergy with all the partners. The resulting research work will contribute to informing public decision-making. Participatory science initiatives may be initiated with actors of the socio-economic and cultural eco system of the project
The activity will be evaluated in particular on the basis of scientific production (publications, software, patents, etc.), on institutional and private partnerships formalized by contracts, on international presence, on the promotion of work to multidisciplinary scientific communities, on innovation and its transfer to society and on scientific dissemination to non-specialist audiences.
