High temperature resistant ceramic matrix composites and environmental barrier coatings
The invention relates to a high temperature resistant ceramic matrix composite and an environmental barrier coating. High-temperature mechanical parts, more particularly articles capable of operating in high-temperature environments, including for example turbines of gas engines, may be formed from a high-temperature ceramic matrix composite comprising: a silicon-containing ceramic substrate; an environmental barrier coating system including a silicon-containing bond coating; and a diffusion barrier layer of carbide or nitride between the substrate of the article and the silicon bond coat of the environmental barrier coating system. The diffusion barrier layer selectively prevents or reduces diffusion of boron and impurities from the substrate to the bond coat of the environmental barrier coating system.
本发明涉及耐高温陶瓷基质复合材料及环境障碍涂层。高温机械部件，更特别是能在高温环境下工作的制品，包括例如燃气发动机的涡轮，可以由高温陶瓷基质复合材料形成，该高温陶瓷基质复合材料包括：含硅的陶瓷基材；包括含硅粘合涂层的环境障碍涂层体系；及位于该制品的基材和环境障碍涂层体系的硅粘合涂层之间的碳化物或氮化物的扩散阻碍层。该扩散阻碍层选择性地防止或减小硼和杂质从基材向环境障碍涂层体系的粘合涂层扩散。
