摘　　要：利用激光熔覆技术,在Q235 A钢表面上制备了镍基Ni60合金涂层。研究了激光扫描速度对熔覆层显微硬度的影响。分析了熔覆层和基体的摩擦磨损性能。结果表明:随扫描速度的增加,熔覆层的显微硬度增加。在扫描速度为5 mm/s时,熔覆层的摩擦磨损性能为基体的3.Nickel-based Ni60 alloy coating on Q235A steel surface was prepared by laser cladding. The effects of laser scanning speed on the microhardness of the cladding coating were researched. The friction and wear properties of the cladding coating and Q235A steel were analyzed. The results show that with the increase of scanning speed, the microhardness of the cladding coating increases. Under the scanning speed of 5 mm/s, the friction and wear properties of the cladding coating is 3.47 times of the matrix.
