摘要
本文研究了Ｍ－Ｃｒ－Ａｌ－Ｙ合金（Ｍ＝Ｎｉ，Ｃｏ，Ｆｅ）激光熔覆层的显微组织，微区成分及抗氧化性。氧化增重试验结果表明，Ｍ－Ｃｒ－Ａｌ－Ｙ涂层具有比１Ｃｒ＿（１８）Ｎｉ＿９Ｔｉ不锈铜低得多的氧化增重和氧化速率，其中以Ｃｏ－Ｃｒ－Ａｌ－Ｙ涂层为最好，其次依次为Ｎｉ－Ｃｒ－Ａｌ－Ｙ，Ｎｉ－Ｃｏ－Ｃｒ－Ａｌ－Ｙ＿２Ｏ＿３，Ｆｅ－Ｃｒ－Ａｌ－Ｙ．
This paper deals with the microstructure ,microanalysis and oxidation behavior of laser cladding M-Cr-Al-Y alloys(M=Ni,Co,Fe).The result of oxidat-ing tests shows that the oxidation gain and rate of MCrAlY coatings are far less than that of 1Cr18Ni19Ti stainless steel.Among the MCrAlY coatings,the oxidation be-havior of the CoCrAlY coating is the best and others,in turn,are NiCrAlY,NiC-oCrAlY_2O_3and FeCrAlY coatings.
