摘　　要：以3Cr2W8V模具钢为研究对象,通过表面镀膜和电子束表面合金化处理的方法对模具钢进行了表面改性研究,分析了镀Ti膜、镀CrN膜和镀TiN膜后材料的表面组织形貌和性能随电子束改性参数的变化。研究结果表明,对模具钢进行表面合金化的电子束改性可以极大提高和改善表面组织结构和性能。Taking 3Cr2W8 V mold steel as research object, the surface modification of die steel was studied through the surface coating and electron beam surface alloying, the morphology and properties changing with the variety of parameters of electron beam modification on the Ti film, CrN coated and TiN film were analyzed. The results show that, the microstructure and properties of the surface tissue can be greatly enhanced by electron beam modification on the surface of die steel.
