Synthesis and implementation of coatings based on High Entropy Alloys

Closed

Today, to survive, the metallurgical sector must be in a position to meet the strategic innovation needs of priority application markets (automotive, mechanical, aeronautics). It is essential that new high-performance materials be developed to broaden the scope of applications to areas offering higher added value, while ensuring compliance with increasingly stringent environmental standards. To meet these expectations, the ALLIHENTROP project proposes to develop high-performance coatings from an emerging class of materials, ALLIages with High ENTROPy. These are alloys with complex compositions that contain a large number of metallic elements in equal or adjacent proportions. These materials have unique properties and are designed in the form of coatings in order to provide functionality to a metal part or to improve its performance and thus enhance support or structural materials with low added value. The challenge is to show the possibility of taking these high entropy alloys from the scale of the research laboratory to the pre-industrial scale.
