摘　　要：热障涂层利用陶瓷层的隔热性和抗腐蚀性可以有效保护航空发动机或陆用燃气轮机中热端部件的合金基体。然而,不断追求更高的服役温度会导致表面涂层的降解、分层和过早失效。为了满足未来先进热障涂层系统的服役需求,必须开发新的陶瓷材料。本文综述了近年来先进热障涂层陶瓷材料的研究进展,包括氧化钇部分稳定氧化锆(Yttria partially stabilized zirconia,YSZ)、A_(2)B_(2)O_(7)型化合物、稀土钽酸盐、稀土磷酸盐、高熵稀土陶瓷材料、磁铅石型六铝酸盐氧化物和自愈合材料,分别归纳了它们的性质和性能,总结各种材料现阶段发展的优势和不足,最后展望了热障涂层材料的发展方向,为开发新的热障涂层提供指导。Thermal barrier coatings(TBC)utilize the adiabatic and corrosion resistance of ceramic coatings to effectively protect the alloy matrix of hot components in aero or land-based gas turbines engines.However,the constant pursuit of higher operating temperatures can lead to degradation,delamination,and premature failure of surface coatings.To meet the needs of future advanced TBC systems,new ceramic materials must be developed.This paper reviews recent research advances in ceramic materials for advanced thermal barrier coatings,including YSZ(Yttria partially stabilized zirconia),A_(2)B_(2)O_(7)–type compounds,rare earth tantalates,rare earth phosphates,high entropy rare earth ceramic materials,magnetite type hexa-aluminate oxides and self-healing materials with summarizing their properties and performance respectively,and the advantages and shortcomings of each material at the present stage of development.Finally,the development direction of thermal barrier coating materials is foreseen to provide guidance for the development of new thermal barrier coatings.
