摘　　要：热障涂层材料广泛应用于发动机热端部件的热防护,能有效提高航空发动机热端部件的工作温度和使用寿命。目前商用的热障涂层材料为氧化钇部分稳定氧化锆,但其在服役温度高于1200°C时会发生相变而失效,难以满足新一代航空发动机对热障涂层的性能要求。因此,寻找新型热障涂层材料及其服役性能研究一直是近年来的热点。本文综述了近年来氧化钇稳定氧化锆、钙钛矿氧化物、烧绿石氧化物以及稀土硅酸盐材料的研究进展,并展望了热障涂层材料的未来发展趋势。Thermal barrier coatings are widely used in protecting the hot parts of gas turbine engines,so as to improve its working temperature and service lifetime.At present,the commercially available thermal barrier coating material is Y2O3 partially stabilized ZrO2.However,it will undergo the phase transformation and be failure at temperatures above 1200°C,not satisfying the performance requirements of the next generation aircraft engines.Therefore,a great many efforts are made to search for new thermal barrier coating materials with improved service performances in recent years.In this review,we summarized the recent progress of yttria-stabilized zirconia,perovskite oxides,pyrochlore oxides and rare earth silicate as thermal barrier coatings.
