探讨了ＧＣｒ１５ 钢固体粉末铬钒共渗工艺参数，并运用金相、硬度、扫描电镜能谱及波谱分析、Ｘ射线结构分析、耐磨及脆性等试验方法，测定了共渗层的组织、相结构、渗层硬度分布、磨损及脆性等特性。结果表明，该共渗渗层组织均匀，结构致密，具有高硬度、良好的滑动摩擦磨损性能及较低的脆性等。应用于冷作模具，获得了高的使用寿命。 The technological parameters of GCr15 steel solid powder chrome vanadinizing were discussed. The microstructure, phase and microstructure of the co-permeation layer were measured by metallographic examination, hardness measurement, scanning electron microscopy and spectroscopy, X-ray structure analysis, wear resistance and brittleness test. Structure, distribution of hardness distribution, wear and brittleness and other characteristics. The results show that the infiltration layer has the advantages of uniform structure, compact structure, high hardness, good sliding friction and wear properties and low brittleness. Used in cold die, get a high life.
