摘要(Abstract)：

为了研究(Ni60A+Si)粉末的质量分数、电流和熔覆速度对熔覆层组织和性能的影响,用Ni60A粉末、Cu粉末和Si粉末通过氩弧熔覆在ZL104合金上。利用电子扫描显微镜和X射线衍射仪分析熔覆层的显微组织、颗粒分布以及物相组成,利用显微硬度计和摩擦磨损试验机测试涂层的性能。结果表明,熔覆层的耐磨性、显微硬度和均匀性取决于(Ni60A+Si)粉末在混合物中的比例。实验获得表面光滑、界面结合良好和无裂纹的熔覆层,其显微硬度为390~680 HV,滑动摩擦系数为0.52~0.3。

关键词(KeyWords)： 氩弧熔覆;(Cu,Ni)固溶体;显微组织;耐磨性;显微硬度
