Research Status and Development Tendency of Thermal Barrier Coatings

Thermal barrier coatings (TBCs) become one of the most advanced coatings for high-temperature protection presently, which show excellent thermal barrier effect and high-temperature oxidation resistance. In this paper, the research status of ceramic materials, metal-bonding materials, construction, preparing technology and failure mechanism of TBCs are reviewed. Finally, the development tendency of TBCs is presented.
