Abstract: Thermal barrier coating has good thermal insulation effect and high temperature oxidation resistance, which can significantly increase the service temperature and life of high temperature components in aeroengines. The development of advanced aeroengine has put forward higher requirements for the protective effect and service life of ceramic thermal barrier coating materials. The research progress of thermal barrier coating system for advanced aeroengine is reviewed. The ceramic layer and bond layer material system and preparation technology of thermal barrier coating at home and abroad in recent years are described in detail, while the failure of coating is analyzed. The research and application prospect of the next generation high-performance thermal barrier coatings for aeroengine are prospected.
