摘　　要：利用激光熔覆技术,在45钢表面制备(V_(2)O_(5)+B_(2)O_(3)+C)镍基熔覆层。利用扫描电镜对熔覆层进行显微组织分析,利用显微硬度仪测试熔覆层的显微硬度。结果表明:在1.6 kW功率下,含量20%(V_(2)O_(5)+B_(2)O_(3)+C)的镍基熔覆层硬度最大,平均值高达1350 HV0.3,提高了熔覆层的硬度和耐磨性。(V_(2)O_(5)+B_(2)O_(3)+C)Ni-based cladding layer was prepared successfully by laser cladding on steel 45 substrate.The microstructure of the cladding layer was analyzed by scanning electron microscope,and the microhardness of the cladding layer was measured by microhardness meter.The results show that the microhardness of mass fraction of 20%(V_(2)O_(5)+B_(2)O_(3)+C)Ni based cladding layer is maximum in 1.6 kW power,and the average value of the microhardness is up to 1350 HV0.3.The hardness and wear resistance of the cladding layer is greatly improved.
