中文摘要: 随着航空发动机向大推力、高推重比发展,发动机涡轮进口温度进一步升高,要求高压涡轮用可磨耗封严 涂层的工作温度能够达到 1000℃以上,超过了金属基封严涂层的应用极限,因此陶瓷基高温封严涂层近年来引 起了研究者的广泛关注。本文从陶瓷基封严涂层的研究背景、涂层材料与制备工艺、涂层组织性能调控、涂层孔 隙率对性能的影响以及新概念陶瓷可磨耗涂层等几个方面介绍了陶瓷基高温封严涂层的研究现状,阐述了陶瓷基 封严涂层研究的重要意义和关键问题。
Abstract:With the development trend of aero-engine towards higher thrust/weight ratio, the turbine inlet temperature further raises, and the working temperature of the abradable seal coating used in high pressure turbine has reached 1000℃ above. Such a high temperature has exceeded the capability of the metal-matrix seal coating. So ceramic-matrix seal coating has attracted wide attention of researchers in recent years. In this paper, the research status of ceramic high-temperature sealing coatings was briefly introduced. The research background, coating materials and preparation technology, the regulation of coating microstructure and properties, the effect of coating porosity on properties, and the new concept of ceramic abradable coatings has been reviewed. Additionally, the significance and key issues for ceramic seal coating has been discussed as well.
