The effects of TaC content on microstructure, hardness and oxidation behavior of the composite coatings were studied. The results showed that the composite coatings were composed of superfine γ columnar dendrite and large TaC particles dispersedly distributed. The hardness was enhanced but oxidation resistance of the composite coatings was reduced with increasing TaC contents. 关键词：MCRALY 复合涂层电火花沉积金属基 TAC 抗氧化行为 TAC 微观结构
