摘要
对稀土镁球铁凸轮轴激光热处理硬化层的组织和耐磨性进行了分析 ,并探讨了磨损机理 ,激光处理后的凸轮轴变形小 ,具有良好的耐磨性 。
The Paper makes an approach to the microstrusture and the wear resistance of the hardening layers gainde by the laser heat treating for cam shafts made of the rare earth magnesium nodular graphite cast iron, and analyses wear mechanism The research result indicates that the cam shaftsof the laser heat treating deform little, and have good wear resistance It hasgreat significance to the actual application of the rare earth magnesium nodular graphile casl iron
