摘　　要：以钨极氩弧为热源,原位合成金属陶瓷涂层。观察分析涂层的组织结构,并测量涂层的硬度及耐磨性。和母材相比,涂层的硬度得到很大提高,涂层的耐磨性是对照试样的1.15倍。由此可见,利用钨极氩弧为热源,可以得到耐磨性较好的硬质涂层。The ceramic coating is in-situ synthesized during the reaction of the alloy powders employing the TIG powder surfacing.The microstructure and morphology of the ceramic coating is observed and analyzed.The composite coating's hardness is much higher than the base metal hardness,the wear resistance of the sample is 1.15 times that of the comparative sample.The results of the thesis show that we can get good performance of high-temperature coating by heating with TIG.
