摘　　要：利用MM-200摩擦磨损试验机,在油润滑条件下对Cr-Mo-V合金铸铁表面渗硫及掺Cr的DLC处理后的磨损性能进行了研究,并比较了两种处理方式的磨损性能差异。利用扫描电子显微镜观察磨痕宽度和磨损形貌,结果表明:DLC处理优于渗硫处理的耐磨性能,说明将DLC技术运用于合金铸铁,其减摩耐磨效果更好。Wear resistance properties of sulphurized and Cr-diamond like carbon（DLC） treated Cr-Mo-V gray cast iron were investigated under the condition of oil lubrication on MM-200 wear tester and compared. The wear width and the wear morphology were observed by scanning electron microscope（SEM）.The results showed that the wear resistance of DLC treated alloy was better than sulphurized alloy,the Cr-Mo-V gray cast iron obtained better antifriction and antiwear effect after using DLC technique.
