Development of advanced surface technology for extended resistance in extreme environment

Objective

ASTERIXE is aiming at developping innovative combined surface treatments promoting a technological breakthrough for high performances in the field of Environmental Barrier Coatings (EBC's). These coatings play a key role in high temperature, highly corro sive environments and high mechanical stress conditions. The goal of the project is to open new routes of surface engineering by combining coating deposition and advanced post treatment technologies (pulsed e-beam (PEB) and laser). The understanding of t he phenomena interacting on the coating composition and structure will be improved all along the project with the creation and optimisation of a model predicting the coating composition and structure after post treatment.The coatings will be deposited by different processes, electrochemical, spray or vapour deposition, the process choice being mainly dependent on the elemental composition needed to fulfil the application requirements. The pulsed e-beam and laser treatment will be used to give the coatin g its final structure and morphology together with an interface melting promoting coating to base material alloying. As a result, the coating process will be optimised in one hand, by using the results of the predicting model, and in other hand, by testi ng new combinations with respect to the chemical composition (new chemical systems, hybrid layers, self repairing coatings?). This will be obtained through:-a new concept of interface treatment leading to enhanced coating adhesion strength by simultaneou sly melting of the coating and the substrate surface. -a new process of extremely fast surface quenching from the melt leading to values of density and toughness of the surface layer close to the theoretical "bulk" values without affecting the substrate material. -a new route to obtain still unavailable chemical compositions by combining multi layer coating and surface alloying. -a new route for self diagnostic coating (or "sensor coating")'
