HIGH ENTROPY CERAMIC FOR PROTECTION OR MULTI-LAYER IFC
Abstract:
A ceramic matrix composite includes a fiber, a first interface coating layer disposed adjacent to an outer surface of the fiber, and a first protective layer disposed outward of the first interface coating layer and the fiber. The first protective layer comprises a high entropy ceramic. A method of protecting a fiber of a ceramic matrix composite includes depositing, by chemical vapor deposition or chemical vapor infiltration, a first interface coating layer on the fiber; and depositing, by chemical vapor deposition or chemical vapor infiltration, a first protective layer outward of the first interface coating layer. The first protective layer comprises a high entropy ceramic.
