Work Package 11: Interactions with Environment (p. 81 of Annex 1)
WP Leader: Marie Geneviève Barthès-Labrousse, CNRS Vitry/Thiais, France

| Objectives (a) Scientific: (i) To undertake chemical analysis and physical-property studies of the surface of complex metallic alloys before and after they have interacted with the environment. This concerns e.g. oxidation, corrosion, contact to liquids and lubricants. (ii) To monitor the evolution of the technologically relevant properties, e.g. alloy composition, microstructure, hardness, friction, adhesion, interaction with hydrogen, when ageing under operation conditions. (iii) To tackle specific surface-related problems in the applications area. This also includes rigorous test with respect to environmental harmlessness. The goal is to form a knowledge basis, reaching from surface physics and chemistry to the manufacturing of realistic materials proving successful on the market with respect to the combination of a number of useful properties. (b) Integration: (i) Contribute to VIL D: Surface physics, chemistry and nanoscience the know-how and competence on properties of CMAs in the environment and assist this way in the establishment as a joint effective facility (platform-like part) of the Network making it particularly competitive. (ii) To act as a “Service Centre” for the solution of surface-related problems which arise in the work of VIL E (Coatings) and VIL F (Applications). And related to this (iii) contribution to transfer of knowledge and service to companies acting in the areas of surface technology. |
| Description of work (a) Scientific: First goal: Provision of chemical analysis of the surface composition, including depth profiling, of CMA surfaces before and after exposure to ambient atmosphere as well as environmental atmospheres encountered in practical use of CMA materials (friction, adhesion, corrosion, interaction with hydrogen). Second goal: Detailed study of the fundamental properties of the oxide layers grown on CMA model materials, both as bulk CMA substrates and as nanoscale thin films in order to understand the coupling between substrate and surface properties in the presence of an environmental atmosphere. This study will have direct relevance to (a) the development of CMA-based interdiffusion layers at nanoscale relevant to applications in microelectronics and to (b) solutions preventing the formation of a diffusion barrier to hydrogen on hydrogen-storing materials as studied in VIL F. (b) Interaction: To form a bridge between the research achieved in VIL D and that carried out in VIL E (Thin films) and VIL F (Applications). The Work Package leader (deputy director of VIL D) will liase closely with the directors of VIL D & F to optimise the use of resources and to take advantage of complementarity of expertise and interests where appropriate. The work will be of relevance for materials selection in VIL A contributing to find strategies for improved CMAs to be prepared in VIL A and investigated in turn in the other VILs. (c) Integration: VIL D will act as a Service Centre for the other VILs, in particular VILs E and F where surface-related problems can be of paramount importance. These can be tackled at maximum efficiency. Exchange visits of Network personnel will take place with the twin goals of sharing of expertise and dissemination of good practice. |
| Deliverables (a) Scientific: D11-1: Report on surface characterisation of samples (as prepared by VILs A and E) for dissemination to participants in VILs D, E, F. D11-2: Knowledge on structure and properties of aged CMA surfaces published in international journals. (b) Interaction: D11-3: Joint service centre between VIL D, E & F: D11-4: Internal regulation and report. (c) Integration: D11-5: Topical meetings (2 in 18 months, one dedicated to private companies): D11-6: Reports and proceedings. |
| Milestones (a) Scientific: Month 6: M11-1: Distribution of samples of selected CMA materials to participants in VIL D; Month 12: M11-2: First results on oxidation and on the properties of the oxide surfaces; Month 18: M11-3: Results on effect of aging on the properties of the oxidised surfaces. (b) Interaction: Month 6: M11-4: Establish interaction and feedback with other VILs. In particular: Organize close interaction and joint decision-making with VILs E and F. (c) Integration: Month 6: M11-5: Completion of the VIL D workshop event. Month 12: M11-6: Definition chart of the ways to access and collaborate with the service centre. Month 18: M11-7: VIL D established; demonstration of good examples to achievements and collaborations. Strategy of further improvement decided. |
