研究模具钢Ｈ１３熔盐Ｃｒ—ＲＥ共渗对表面显微组织特征及其性能的影响，渗剂中加入适量稀土可使渗速提高２０％～５０％，Ｃｒ－ＲＥ共渗优于单一渗Ｃｒ，可明显提高模具表面硬度、抗氧化能力和耐磨性能。
The effect of Cr-RE co-permeation on the microstructure and properties of molten steel was studied. The addition of appropriate amount of rare earth in the penetrant can increase the permeation rate by 20% ~ 50% , Can significantly improve the mold surface hardness, oxidation resistance and wear resistance.
