Aim of Genesis is to develop new environmental barrier coatings (EBC) systems which, by exploiting nanostructured materials, functional gradient architectures and economically efficient deposition techniques such as thermal spraying, offer a cost/performance ratio to favor an ever-increasing use of SiC(f)/SiC composites in aeronautical propulsion. To this end, the coatings must satisfy a wide range of requirements: not only resistance to water vapor, but also to the thermal cycles to which an aeronautical engine is subject, to erosion by atmospheric dust, and to chemical attack by molten silicates.

Innovative aspects tackled in GAG2ARIN: a nanostructured graded RE-silicate system topped by refractory oxides and applied by atmospheric plasma spray
