摘要
本文研究了稀土元素对离子硫、氮、碳共渗层金相组织,渗层深度及耐磨性能的影响。结果表明,一定量的稀土元素对离子硫、氮、碳工艺具有较明显的催渗作用,使渗层深度提高25%以上,改善了表面组织,使表面硬度增强,耐磨性能提高2倍以上。
The effect of Re elements on ion sulpe-nitricabinzing microstructure nitriding depth andweer resistance was carried out. Experimental results show that the Re elements have in-ceased nitriding depth over 25%, improved nitriding microstructure and enhanced hardness.The wear resistance has increased more than double times.
