摘要:

随着航空发动机技术的不断进步,涡轮部位温度不断攀升,对涡轮的耐高温性能以及相应的防护措施也提出了更为严苛的要求。封严涂层通过自我牺牲式的磨耗,有效控制转子与静子之间的间隙,同时保护叶片叶尖免受损害,这对于提升发动机效率、减少油耗以及延长服役寿命具有至关重要的意义。本文综述了耐1 000℃以上陶瓷基高温可磨耗封严涂层材料体系,并重点介绍了陶瓷基高温可磨耗封严涂层的基本力学性能、热稳定性能及可磨耗性能。总结了高温可磨耗封严涂层目前所面临的挑战,对未来发展方向做出展望。

Abstract:

With the continuous progress of aviation technology, the temperature of the turbine part is constantly rising, which puts forward more stringent requirements on the high temperature resistance of the turbine and the corresponding protective measures. Abradable sealing coatings effectively control the gap between rotor and stator through self-sacrificing abrasion and protect the blade tips from damage, which is of vital significance for improving engine efficiency, reducing fuel consumption and extending service life. This paper introduces the high-temperature abradable sealing coating above 1 000 ℃, and focuses on analyzing the basic mechanical properties, thermal stability and abradable properties of high-temperature abradable sealing coatings. It summarizes the challenges faced by high-temperature abradable sealing coatings and gives an outlook on the future development direction.
