摘　　要：探讨了Cr12MoV冷作模具钢的中性盐浴渗钒处理工艺,运用扫描电子显微镜、显微硬度计、摩擦磨损试验机等试验分析方法,观察、测定了渗层的组织、厚度、硬度分布、相对耐磨性等特性。结果表明,该渗层组织均匀,结构致密,具有很高的显微硬度和较高的耐磨性。Vanadinizing process for Cr12MoV steel in the neutral salt - bath was discussed. By using Analytical Scanning Electron Microscope, Microhardness tester, Wear and abrasion test machine, we observed and measured the coating microstructure, the coating thickness, the hardness distribution along depth and relative frictional resistance and so on. The results show that the coating is essentially has uniform structure, high microhardness and good frictional resistance. hardening compact,
