Abstract:
SiCf/SiC composite is disruptive material for the hot-section components in new generation aviation engine. High temperature coatings, including environmental barrier coating, thermal/environmental barrier coating, as well as abradable coating, can protect various SiCf/SiC components against harsh thermal and chemical attacks in combustion environment. Rare earth silicate high temperature coatings are reliable up to the surface temperature of 1350℃. The key technology depends on coating design, processing of thermal spray powders, and plasma spray technology. This talk presents the recent progresses of rare earth silicate high temperature coatings. The developments support the applications of SiCf/SiC composite in combustion environment.
