摘要
随着航空发动机使用环境要求不断提升,现有热障涂层技术在热物理性能和热稳定方面难以满足现代航空发动机的发展需求。本文介绍了热障涂层制备工艺,热障涂层材料的设计和选择,以及热障涂层的失效机理;归纳了热障涂层新型材料在材料热物理性能及材料稳定性方面的研究进展。指出了后续航空发动机新型热障涂层的发展趋势,为后续研究提供了方向。
With the increase of the operation environment requirements for aero-engine,the thermal barrier coating technology is difficult to satisfy the development requirement of aero-engine in the aspects of thermo-physical properties and thermo-stability.The preparation techniques of thermal barrier coating,design and selection of thermal barrier coating material,and failure mechanism of thermal barrier coating are introduced.The up-to-date research of material for better thermo-physical properties and better performance in CMAS(CaO-MyO-Al 2O 3-SiO 2)resistance are discussed,which provide a direction for further research on thermal barrier coatings.
