航空发动机可磨耗封严涂层技术研究及性能评价

摘要

综述了国内外封严涂层的研究现状,介绍了航空发动机封严涂层的结构和应用特点,重点讨论了可磨耗封严涂层性能评价和技术研究现状.比较了各种涂层材料、评价方法的优势与不足,指出了可磨耗封严涂层的应用潜力及研究发展方向.提出了我国在可磨耗封严涂层技术研究及性能评价方面今后的发展方向,即涂层制备方法、结构研究、高温涂层研究和仿真技术等.%The general situations of abradable coating in China and abroad were reviewed in this re-search,and the structure and application features of abradable coating in aeroengine were also intro-duced.The performance evaluation and technological researches of abradable coating were empha-sized,too.The advantages and disadvantages of different abradable coatings and evaluation methods were compared.The application prospects and future research directions were put forward and clari-fied.The further focused research directions of both the abradable coating technological research and performance evaluations in China were declared,the study on coating preparation,structure of the coating,high temperature coating research and simulation technology need further development.
