本文研究了16Mn钢表面激光熔敷处理对耐磨性的影响及熔敷层的组织结构与耐磨性的关系.结果表明激光熔敷Ni基合金,尤其含有TiC或WC粉末能大幅度地提高低合金钢的耐磨性. In this paper, the effect of laser cladding on the wear resistance of 16Mn steel and the relationship between the microstructure and wear resistance of the cladding layer were studied.The results show that laser cladding Ni-based alloy, especially containing TiC or WC powder can greatly improve Low alloy steel wear resistance.
