摘要/Abstract

摘要： 采用激光熔覆技术在65Mn钢表面制备了Cr₃C₂/Ni60AA复合熔覆层。利用X射线衍射仪、扫描电镜、维氏显微硬度计、干砂橡胶轮磨损试验机、冲击磨损试验平台及盐雾试验箱等试验设备,研究了10%Cr₃C₂的添加对Ni60AA熔覆层物相组成、显微组织、显微硬度、耐磨性能、耐冲击磨损性能及耐蚀性能的影响。结果表明,Cr₃C₂部分溶解于熔覆层中,形成了Cr₇C₃及Cr₂₃C₆强化相,Cr₃C₂/Ni60AA复合熔覆层物相由γ-Ni、Cr₂₃C₆、CrB、FeNi₃、Ni₃B、Cr₃C₂及Cr₇C₃等相组成。相比Ni60AA熔覆层,复合熔覆层中少量未熔解的Cr₃C₂颗粒和弥散分布的Cr₇C₃及Cr₂₃C₆增强相使复合熔覆层的显微硬度、耐磨性能及耐冲击磨损性能均优于Ni60AA熔覆层,但耐蚀性能略有降低。

Abstract: Cr₃C₂/Ni60AA composite coating was prepared by laser cladding on the surface of 65Mn steel. Effect of 10% Cr₃C₂ addition on phase composition, microstructure, microhardness, wear resistance, impact wear resistance and corrosion resistance of the Ni60AA coating was investigated by means of X-ray diffractometer, scanning electron microscope, Vickers microhardness tester, dry sand rubber wheel wear tester, impact wear test platform and salt spray test chamber and other test equipment. The results show that the Cr₃C₂ is partially dissolved in the Ni60AA coating, and the strengthening phases of Cr₇C₃ and Cr₂₃C₆ are formed. The Cr₃C₂/Ni60AA composite coating consists of γ-Ni, Cr₂₃C₆, CrB, FeNi₃, Ni₃B, Cr₃C₂ and Cr₇C₃. Compared to the Ni60AA coating, the microhardness, wear resistance, and impact wear resistance of the composite coating is higher, but the corrosion resistance is slightly reduced, which is attributed to a small amount of unmelted Cr₃C₂ particles and dispersed Cr₇C₃ and Cr₂₃C₆ reinforcing phases.

Key words: laser cladding, Cr₃C₂/Ni60AA coating, microstructure, wear resistance, impact wear resistance
