| 摘 要： | 利用表面机械研磨处理（SMAT）技术对GCr15钢制备了纳米结构表层。通过X射线衍射及透射电镜分析了其组织结构,利用UMT—2M型摩擦磨损试验机测试了GCr15钢处理前后的摩擦磨损性能。分析结果表明,试验中处理时间为15 min是提高其摩擦磨损性能的最佳工艺条件。磨痕形貌的扫描电镜观察表明,随着磨损深度的增加,主导磨损机制由黏着磨损转变为磨粒磨损。

| Abstract: | Nano-structured layers are fabricated on the surface of GCr15 steel by using the surface mechanical attrition treatment(SMAT).The microstructure of the surface layer was characterized by means of X-ray diffraction(XRD) and transmission electron microscopy(TEM).The friction and a wear properties are measured by a UMT-2 friction and wear tester.The analytical results show that the 15 min treatment time in this experiment is the best way of improving the friction and wear properites of GCr15 steel.The SEM obse... |
