With the increase of turbine inlet temperature (TIT) for aeroengine, superalloy can not meet the work requirements. Ceramic matrix composites (CMC) with SiC/SiC as a typical material can increase the temperature by 150-200 ℃, and the density is 1/3, compared with superalloys. Therefore, CMC is an important direction for next generation aeroengine. However, the CMC can be oxidized at high temperatures and reacts with water vapor. Therefore, high performance environmental barrier coating (EBC) protection is required. In the past 10 years, APS and PS-PVD EBC coatings were carried out. Besides, the Al surface modification technology is also proposed. The deposition mechanism of APS and PS-PVD EBC was studied. And the corrosion resistance and high temperature oxidation of EBC coating were studied.
