35CrMo钢曲轴离子软氮化的研究

Study on IonNitrocarburizing Process of 35CrMo Steel Crankshaft

研究了３５ＣｒＭｏ钢曲轴离子软氮化后的显微组织和特性。结果表明，经离子软氮化的材料具有表面硬度高、化合物层厚和渗氮层深的特点，并且比离子氮化的材料具有更优良的耐磨性和疲劳强度。

The microstructure as well as characteristics of the ionnitrocarburization of 35CrMo steel crankshaft was studied. The results show that the microhardness is improved and hardened layer deepened after ionnitrocarburization. The wear resistance and fatigue property of ionnitrocarburized steel are better than those of ionitrided steel.
