摘　　要：本文报导在铜表面激光熔覆镍基硬面合金表面改性的研究结果。用ＯＭ、ＴＥＭ、ＸＲＤ研究了合金层的微观组织特征，用ＥＤＳ－ＳＥＭ的研究了熔覆合金层的成份分布；用相分析、ＸＲＤ、比色法、化学分析研究了合金层的碳化物（硼化物）种类、数量、分布；还研究了激光熔覆合金层的显微硬度和耐磨姓。This paper reports the results ofinvestigation on the wear resistance of laser Gladed3Cr2W8V with nickel-based hardfacing alloys。Microstructure of the claddings was investigated byOM,TEM and XRD,and the con1position variationof claddings was measured by EDS-SEM also,The type,composition and quantity of carbides and borides of the cladding were ascertained by phase analysis,XRD and chen1ical analysis.In comparision withthe steel 3Cr2W8V,the microh8rdness and wear resistance of the claddings were measured。

关 键 词：3CR2W8V钢 激光熔覆 镍基硬面合金 耐磨性 表面改性
