摘　　要：研究激光熔敷陶瓷（ＺｒＯ２－Ｙ２Ｏ３）涂层在高温下的抗氧化性，通过金相、ＳＥＭ、ＴＥＭ、ＥＤＡＸ和Ｘ线衍射等测试方法，对涂层在激光熔敷前后的形貌、结构、组织进行分析，并比较高温下的抗氧化性，讨论涂层在高温下对基体保护的机理。This paper deals with the high-temperature oxidation behaviour of steel substrates under the protection of laser melted oxide ceramic (ZrO2-Y2O3) coating. The morphology,content of elements, microstructure, and phase structure of coatings before and after laser melting are studied by optical microscopy, SEM, TEM, EDAX and Xray diffraction. There is a comparison of oxidation resistance between plasma sprayed coatings and laser melted coatings. The possible mechanism of the coatings of the two states against oxidation is discussed.
