摘　　要：随着航空技术的不断进步,航空发动机涡轮前温度不断攀升,对热端部件的耐高温性能及相应的冷却手段也提出了更高的要求。热障涂层作为热端部件(尤其是涡轮叶片)隔热冷却性能的关键技术之一,其研究和应用受到广泛关注。综述了氧化钇部分稳定的氧化锆(YSZ)基热障涂层的研究进展,重点探讨了YSZ涂层的改性方法、制备技术及失效机理。通过涂层设计的材料(如稀土或过渡金属氧化物等)角度,综述了它对YSZ涂层热导率、高温相稳定性和抗烧结等性能的影响,并详细探讨了单元氧化物掺杂和多元氧化物共掺杂对YSZ涂层改性的机理和影响。同时,介绍了大气等离子喷涂(APS)、电子束物理气相沉积(EB-PVD)和等离子喷涂-物理气相沉积(PS-PVD)等主要YSZ涂层制备技术,对比了它们的优势和局限性。此外,探讨了热障涂层的主要失效模式,包括热膨胀系数不匹配、热生长氧化物(TGO)、CMAS腐蚀及Na2SO4+V2O5熔盐腐蚀失效,并总结了热障涂层的失效机理。最后对未来YSZ基热障涂层的发展方向进行了展望。With the relentless pursuit of higher efficiency in aviation,the turbine inlet temperature of aero-engines has been pushing the boundaries,necessitating superior thermal insulation capabilities from hot-end components.Thermal barrier coatings(TBCs),particularly those based on Yttria Stabilized Zirconia(YSZ),have emerged as a pivotal technology for enhancing the thermal resistance and lifespan of turbine blades.The work aims to delve into the research progress of YSZ-based TBCs,providing a detailed analysis of the modification methods,preparation techniques,and failure mechanisms of the coatings.The effects of coating design by doping of rare earth elements or non-rare earth oxides on the thermal conductivity,high-temperature phase stability,and resistance to sintering of YSZ-based coatings are comprehensively discussed in the review.Additionally,a detailed exploration is provided,clarifying the modification mechanisms and significant impacts that single oxide doping and multi-oxide co-doping have on the properties of YSZ-based coatings.The intricate relationship between the atomic mass,ionic radius,and the resultant phonon scattering has been elucidated,providing a theoretical foundation for the design of low thermal conductivity ceramics.The common YSZ-based coating preparation techniques are introduced,including atmospheric plasma spraying(APS),electron beam physical vapor deposition(EB-PVD),and plasma spray-physical vapor deposition(PS-PVD),and their advantages and disadvantages are summarized.APS YSZ-based coatings offer low thermal conductivity due to their porous,layered structure but have issues with low elasticity,weak adhesion,and limited thermal cycle life.EB-PVD YSZ has a robust columnar structure with high strength but the highest thermal conductivity and is susceptible to high-temperature oxidation and corrosion.PS-PVD merges the benefits of the both,enabling the adjustment of the microstructure for rapid,uniform,and dense coating deposition by varying process parameters.In addition,the primary failu
