摘　　要：利用激光熔覆技术在45钢表面制备了Ni20合金熔覆层,通过扫描电镜、X射线衍射等方法,研究涂层相及冲蚀形貌,采用HV-1000型显微硬度计测试熔覆层截面显微硬度,利用自制冲蚀设备对Ni20合金熔覆层耐冲蚀性能进行研究,并得出研究结论。Metallurgical binding and compact alloy layers are prepared by laser cladding technology with Nibased alloy powders on 45 steel. The microstructure and sectional microhardness of the laser cladding is analyzed with SEM,XRD and HV-1000 microhardness tester. The erosive resistance of the coatings is in- vestigated, and a conclusion is drawn.
