MCrAlY涂层在航空发动机热端部件上的应用

摘要

本文关注航空发动机热端部件上应用的高温涂层，包括MCrAlY包覆涂层、粘结层和高温可磨耗封严涂层；综述了国内外关于MCrAlY高温防护涂层、高温可磨耗封严涂层的最新研究进展；讨论了MCrAlY高温涂层未来的发展。%This paper focuses on the application of high-temperature coatings on aeroengine hot-section components,including MCrAlY overlay coatings,bond coatings and high-temperature abradable seal coatings. Recent progesses in MCrAlY high-temperature protective coatings and high-temperature abradable seal coatings are reviewed. The development prospect of MCrAlY high-temperature coatings is also discussed.
