摘要/Abstract

摘要： 系统剖析了传统YSZ热障涂层在高温服役环境下的核心失效机制,其失效主要与高温相变及钙镁铝硅酸盐(CMAS)侵蚀等关键因素相关,难以适配先进航空发动机的严苛服役要求。稀土锆酸盐陶瓷凭借高热膨胀系数、低热导率及卓越的抗CMAS侵蚀特性,成为极具应用潜力的新型替代材料。为此,系统综述了不同构型熵稀土锆酸盐陶瓷在抗CMAS侵蚀方向的研究进展,同时阐释了其抗CMAS侵蚀机制,并明确了构型熵对材料抗侵蚀性能的调控作用。最后指出,未来需重点开展动态工况下的侵蚀动力学探究,进一步完善组分和性能的预测模型,通过深化基础研究与技术攻关,为该类材料在先进航空发动机中的工程化应用提供坚实支撑,推动其从实验室研究向工程应用转化。

关键词: 热障涂层, 稀土锆酸盐陶瓷, 钙镁铝硅酸盐

Abstract: This paper systematically analyzes the core failure mechanisms of traditional YSZ thermal barrier coatings under high-temperature service environments.Its failure is mainly associated with key factors such as high-temperature phase transformation and calcium-magnesium-aluminum-silicate (CMAS) erosion,making it increasingly unable to meet the stringent service requirements of advanced aero-engines.Rare earth zirconate ceramics,endowed with high thermal expansion coefficient,low thermal conductivity,and excellent CMAS erosion resistance,have emerged as highly promising new alternative materials.The paper comprehensively reviews the research progress of rare earth zirconate ceramics with different configurational entropies in the field of CMAS erosion resistance.It simultaneously elaborates on their intrinsic mechanisms of CMAS erosion resistance and clarifies the regulatory role and influence laws of configurational entropy on the material’s erosion resistance performance.Finally,it is pointed out that future research should focus on investigating erosion kinetics under dynamic service conditions and further improving the composition-property prediction model.Through deepening basic research and technological breakthroughs,solid support will be provided for the engineering application of such materials in advanced aero-engines,promoting their transformation from laboratory research to practical engineering applications.
