| 摘 要： | 采用刚玉砂轮在卧轴矩台平面磨床上对65Mn钢进行了磨削淬硬,研究了磨削方式对65Mn钢磨削淬硬层组织、显微硬度、淬硬层深度及其均匀性的影响.结果表明:磨削方式对磨削淬硬层显微组织及其显微硬度无显著影响,淬硬层完全淬硬区均由细小均匀的针状马氏体、残余奥氏体和少量未溶碳化物组成,淬硬层高硬度值均在760～820HV之间;但随着磨削方式的改变,试件淬硬层深度及其均匀性相应改变.采用逆磨+顺磨或顺磨+逆磨+顺磨不仅可以增加磨削淬硬层深度,而且可以提高磨削淬硬层深度的均匀性.

| Abstract: | Based on the grinding-hardening experiment of steel 65Mn with corundum wheel that carried on surface grinding machine with horizontal spindle and rectangular table.The paper studied the effects of grinding method on the microstucture of grinding-hardening layer,microhardness,depth and uniformity of hardened layer.The results showed that: grinding method has no significant effects on the microstructure and microhardness of the grinding-hardening layer,which completely consisted of fine acicular martensites,r... |
