However, corrosive gas and foreign particles in the service environment, such as water vapor/oxygen and some silicate dusts may attack silicon-based ceramics, which finally result in lifetime recession and sometimes severe failure. Therefore, Environ

However, this composite material is susceptible to high-temperature oxidation in oxygen-containing environment. Coating with Si-based ceramics or ultra-high temperature ceramic (UHTC) materials is proven to be an efficient method for impro
