The research status quo of interfacial reactions and interdiffusion at three interfaces of top coat(TC)/ thermally growth oxides(TGO),TGO/bond coat and bond coat/substrate of a thermal barrier coating(TBC) system at elevated temperatures were reviewed.

• 综述了热障涂层(TBC)系统的3界面,即陶瓷层/热生长氧化膜(TGO)界面、TGO/粘结层界面及粘结层/基体界面,在高温服役条件下氧化和互扩散行为的研究现状;
