【Abstract】 Thermal barrier coatings (TBCs) have been widely used in advanced gas turbines to protect hot-section metallic components from corrosion and oxidation at elevated temperatures, and to improve engine life and efficiency. Future improvements in gas-turbine performance will require TBCs with more effective protection and longer operating lifetimes. In this paper an overview is tried on different new ceramic materials covering especially doped zirconia, pyrochlores, aluminates, garnets and perovskites. Finally, the future development prospects of Ceramic coating materials are also proposed.更多还原
