| 摘 要： | 采用网格化激光淬火和低温离子渗硫技术对42MnCr52钢进行复合表面处理,使用洛氏硬度计、扫描电子显微镜、X射线衍射仪和能谱仪对表面改性层进行了表征分析,使用T11高温摩擦磨损试验机对复合处理前后的样品进行了高温摩擦磨损比较试验。结果表明:经激光淬火-离子渗硫复合处理后,在基材表面形成了激光淬火渗硫复合层,具有显著的抗高温摩擦磨损性能。与未处理样品相比较,硬度提高20%左右,摩擦因数降低约10%,磨损失重量减少50%以上。最后对激光淬火渗硫复合层的抗高温摩擦磨损机理进行了探讨分析。

| Abstract: | The grid laser-quenching and low temperature ion sulfurized composite treatment technology is employed on the composite surface disposal of 42MnCr52 steel. The structure, composition, surface morphology and hardness of the composite layer are tested with XRD, EDS, SEM and Rockwell apparatus respectively. T11 tribological tester is used to measure the friction-reducing and wear-resistant properties of the composite layer. The experimental results show that laser-quenching and ion sulfurized composite surface... |
