摘　　要：简要介绍了高温防护涂层的发展进程,特别关注航空航天领域中几种常用的高温涂层,包括扩散涂层、MCrAlY包覆涂层和热障涂层;介绍了新概念涂层和玻璃基复合涂层等特色高温防护涂层;综述了国内外关于包括抗氧化或耐腐蚀涂层、热障涂层和扩散阻挡层等高温涂层的最新研究进展;还讨论了高温涂层未来的发展。The history of protective coatings for superalloys is traced, and the traditional high temperature protective coatings presently used in gas turbine airfoils are described, including diffusion coatings, MCrA1Y overlay coatings and thermal barrier coatings. Several new concept coatings, such as microcrystalline coating, equilibrium coating （EQ coating）, functionally graded coatings and smart coatings, and glass-based high temperature coatings are briefly introduced. Recent progresses in high temperature protective coatings are reviewed, including oxidation and / or corrosion resistant coatings, thermal barrier coatings and diffusion barrier coatings. The most fruitful progresses achieved were in the field of thermal barrier coatings, not only promising top ceramic materials but also advanced processing routes have been extensively investigated. Finally the development prospect of high temperature protective coatings is also discussed.
