摘　　要：为获得45号钢单道单层激光熔覆的理想工艺参数,采用光纤激光器在45号钢表面熔覆了单道镍基合金粉末,通过对比不同工艺条件下所得熔覆层的表面质量、显微组织,并进行显微硬度测试。最终得到一组单道单层激光熔覆的理想工艺参数,为以后激光熔覆成形试验提供了数据参考。In order to obtain the ideal process parameters of No. 45 steel single channel single layer of laser cladding, the fiber laser is used to clad single-channel vickel-based alloy powder on the surface of No. 45 steel by comparing the surface quality of cladding layer and the microstructure in different process conditions and doing microhardness test. Finally a set of ideal process parameters of single channel single layer of laser cladding are obtained to provide reference data for the future experiments of laser cladding forming.
