摘要 |
An article includes a substrate formed of a superalloy, a silicon-based ceramic material and a thermally stable silicon diffusion barrier layer. The thermally stable diffusion barrier layer is intermediate to the substrate and ceramic material and prevents diffusion of silicon or carbon into the substrate. The diffusion barrier coating is any coating that is thermally stable and that prevents diffusion of silicon or carbon across a ceramic material:superalloy interface. In a method of forming an article, a superalloy substrate is formed, a thermally stable diffusion barrier layer is applied onto the substrate and a silicon-based ceramic material is supported by the baffler layer coated substrate. The diffusion barrier layer substantially prevents diffusion of silicon from the ceramic material into the superalloy substrate. |
