采用激光熔覆技术在４５ 钢表面获得镍基合金涂层。研究了激光熔覆涂层工艺、熔覆层的组织结构、硬度和腐蚀－ 冲蚀磨损特性，并用２ Ｃｒ１３ 不锈钢进行了腐蚀－ 冲蚀磨损对比试验。激光熔覆镍基合金涂层已经成功地应用于矿用渣浆泵的平衡盘等零件
Nickel-based alloy coating was obtained on the surface of 45 steel by laser cladding. The laser cladding coating process, the microstructure, hardness and corrosion-erosion wear characteristics of the cladding layer were studied. The corrosion-erosion wear comparison of 2 Cr13 stainless steel was carried out. Laser cladding nickel-based alloy coating has been successfully used in mine slurry pump balancing plate and other parts
