摘要
应用光学金相、扫描电镜、显微硬度和耐磨性测试对两种不同基材电火花表面强化层的组织和性能进行了研究。试验结果表明,表面强化层硬度、表面光洁度和强化时间与选择工艺参数有关;相同工艺参数,含碳量高的基材,得到强化层硬度较高,表现出耐磨性较好。
<abstract>e microstructure and property of electrospark surface strengthening layers of two different parent metals were inverstingated using optical metalogryphy, scanning electron microscope ( SEM) , mircohardness and wear resistance testing. The result showed that the microhardness,finish and time of strengthening layers related to parameter of strengthening technology. The same technology parmeter, strengthening layers of high carbon parent metals with high microhardness and good were - resistance can be obtained.
