英文摘要：

The development of the diffusion barrier in the high temperature coating systems are reviewed in this paper. The mechanism of the diffusion barrier in the high temperature coating systems is explained. The ahility of element diffusion barrier, the influence of diffusion barrier on the interfacial adhesion strength and the preparation cost of the diffusion barrier are discussed. For the practical application in industry, the advantages and disadvantages of these diffusion barriers mentioned are analyzed. The method to improve the interracial adhesion strength of ceramic diffusion barrier on the overlayer or the substrate is proposed.
