Thermal barrier coatings (TBCs) are applied on gas turbine. The applications are driven by the need to reduce the metal temperature, increase the service life and improve the efifciency. In this paper, an overview was focused on the composition structure of TBCs and preparation techniques. In addition, the technology of coating repairing was introduced. The prospect of TBCs for the next generation was also proposed.
