摘　　要：研究了32Cr3Mo1VA钢表面电火花沉积Cr的两极质量过渡机制,从基体的角度将32Cr3Mo1VA钢电火花表面强化分为三个阶段:即电极与基体放电;强化层中第二相逐渐形成到完全建立;强化层中的第二相成为"电极电蚀的对象"。Mass transfer mechanism of Electrospark Deposition was studied based on 32Cr3Mo1VA Steel with Cr Electrode. From the point of view of the substrate it can be divided into three phase： firstly electrospark is generated between the anode and the substrate; secondly the new phase in the hardened coating is being formed gradually until completely formed; thirdly the new phase becomes ＂the cathode＂.

关 键 词：质量过渡 电火花沉积 CR 32Cr3Mo1VA钢
