摘　　要：以氩弧为熔敷热源,在熔敷层中添加Ni基和Fe基自熔合金粉末,利用金相显微镜、硬度计和磨损试验机等仪器设备研究熔敷层的微观组织、硬度和耐磨性能。结果表明,混合合金粉末中当Ni60和Fe60配比为6∶4时,熔覆层的硬度提升明显,耐磨性最好。The microstructure, hardness and wear resistance of clading layer with Ni and Fe base alloy powder were studied by metalloscope, hardness tester and abrasion tester. The results show that, when mixed alloy powder Ni60 and Fe60 ratio is 6∶4, the hardness of the cladding layer significantly improve and get the best wear resistance.
