Due to the increasing demand for higher operating temperatures in gas turbine engines, a reliability problem has emerged on TBCs by the attack of calcium-magnesium-alumino-silicate (CMAS) deposits. These contaminants yield glassy melts adhering to the TBC surface at high temperatures, followed by infiltrating and interacting into/with TBC, which result in its severe degradation and premature failure. The adhesion of molten CMAS and the protection methods are hot and difficult points in the field of thermal barrier coatings. In this paper, the latest research results on CMAS adhesion, infiltration and corrosion resistance of plasma spray-physical vapor deposited thermal barrier coatings are reviewed. The approaches for developing corrosion-resistant TBCs were proposed.
