摘　　要：采用脉冲等离子体爆炸技术对Cr12MoV钢表面进行改性处理,利用扫描电子显微镜、显微硬度计、摩擦磨损试验机对不同处理次数下改性层的组织、耐磨性进行了研究。结果表明:经过脉冲等离子体爆炸技术处理后,材料表面发生熔化并获得均匀致密的改性层。改性层硬度从表面到基体呈现先升高后降低的趋势且硬化层的硬度较基体显著提高。经过脉冲等离子体爆炸技术处理后材料表面的耐磨性得到显著提高。The surface of Cr12 Mo V steel was treated by pulse plasma detonation technics. The surface microstructure was analyzed by scanning electron microscope,the surface properties were measured by microhardness tester and friction wear testing machine. The results show that with pulse plasma detonation treatment,the material surface is melted and an uniform and compact modified layer is obtained on the surface. The hardness of modified layer firstly increases and then decreases from the surface to substrate,and the value of modified layer is harder than substrate. The wear resistance of Cr12MoV steel is improved significantly with pulse plasma detonation treatment.
