| 摘 要： | 热障涂层（thermal barrier coatings，TBCs）能有效的提高航空发动机热端部件的工作温度和使用寿命。目前应用最为广泛的热障涂层材料为氧化钇部分稳定氧化锆（yttria-stabilized zirconia，YSZ），该热障涂层材料在服役温度高于1200℃下会发生相变，严重影响航空发动机的使用寿命和服役安全，难以满足新一代航空发动机的服役要求。本文综述了新型热障涂层材料的研究现状，重点介绍了掺杂改性氧化钇部分稳定氧化锆、烧绿石或萤石结构材料、钙钛矿结构化合物、磁铅石矿结构化合物以及新型黏结层材料的研究进展和发展方向，并论述了热障涂层制备技术的方法原理和优缺点，最后对热障涂层材料和制备方法的发展趋势进行了展望。

| Abstract: | Thermal barrier coatings (TBCs) can effectively improve the operation temperature and service life of aero-engine hot end components. At present, yttria-stabilized zirconia (YSZ) is the most widely used thermal barrier coating materials. Phase transformation of YSZ occurs when the service temperature is higher than 1200℃, which seriously affects the service life and service safety of the aero-engines, and it is difficult to meet the service requirements of new generation of aero-engines. The investigation on the advanced thermal barrier coating materials (TBCs) was summarized in this paper. The research progress of several novel thermal barrier coating candidates were mainly reviewed, such as multiple oxide co-droped YSZ, A2B2O7-type compounds, perovskites, magnetoplumbite compounds, and new bond coating materials. The preparation principles and advantage-disadvantage of thermal barrier coatings were discussed. At last, the development direction of thermal barrier coating materials and preparation technology were also proposed. |
