When the grinding parameters are constant, the depth of hardened layer and.
结果表明:硬化层完全硬化区均由细小的孪晶马氏体和板条马氏体组成,且硬化层的组织形貌及显微硬度无显著变化,但硬化层略粗马氏体相的出现位置有所差异;在磨削用量恒定时,顺磨硬化层的深度以及最大残余压应力均大于逆磨硬化层;在磨削功率恒定时,采用逆磨方式可以获得更深的硬化层;与干磨相比,湿磨硬化层表面残余压应力有所提高,但其硬化层深度减少了约30%。
and with constant working current,the lower scanning speed,the deeper harden layer depth and the higher hardness.
工作电流不变,扫描速度越低,硬化层深度越深、硬度越高。
