摘　　要：目前主要研究的热障涂层陶瓷材料分为氧化物稳定的ZrO2、钙钛矿结构ABO3陶瓷、焦绿石或萤石结构A2B2O7陶瓷、磁铁铅矿结构MMeAl11O19陶瓷及其他先进陶瓷材料5大类。概述了各类材料的研究进展,对热障涂层陶瓷材料今后的发展方向进行了探讨,认为氧化物稳定的ZrO2在热障涂层中的应用地位必将被使用温度更高的新型陶瓷材料所替代。A review was provided of the current status of research and progress of ceramic-matrix thermal barrier coatings,and prospects of which were also suggested.It was pointed out that ceramic-matrix thermal barrier coatings could be divided into five categories,namely oxide stabilized zirconia,ABO3 ceramics with perovskite structure,A2B2O7 ceramics with pyrochlore or fluorite structure,MMeAl11O19 ceramics with magnetoplumbite structure and other advanced ceramics,and oxide stabilized zirconia was to be substituted by novel ceramic materials with higher working temperature in future.
