    摘要: A coated article includes an article (30) having at least one surface and composed of a molybdenum based refractory metal alloy base substrate, a niobium based refractory metal alloy base substrate or a silicon base substrate. A bond coat layer (32) is disposed upon the surface. The bond coat layer (32) includes a molybdenum disilicide base compound and at least one of the following: silicon nitride, silicon carbide or tantalum oxide. A process for coating the article includes the steps of applying upon the article's surface the aforementioned bond coat layer (32). A functionally graded material layer (34) is applied upon the bond coat layer (32). The functionally graded material layer (34) comprises molybdenum disilicide, mullite and at least one of the following: silicon nitride, silicon carbide or tantalum oxide. A thermal barrier coating layer (36) is then applied upon the functionally graded material layer (34).
