Bond coating and thermal barrier compositions, processes for applying both, and their coated articles |
摘要 |
A coated article includes an article 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 is disposed upon the surface. The bond coat layer 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. A functionally graded material layer is applied upon the bond coat layer. The functionally graded material layer comprising molybdenum disilicide, mullite and at least one of the following: silicon nitride, silicon carbide or tantalum oxide. A thermal barrier coating layer is then applied upon the functionally graded material layer.
