摘要
在20钢渗碳过程中，渗碳剂中添加微量稀土元素,对渗碳有明显的促进作用、并提高了渗层的硬度和耐磨性.
There is obvious result from the carburization by addition microadditional rareearth elements to carburizing agent during the carburizing process of 20 steel. The hardnessand the wear resistance of permeable layer tire improved. At the same time a proposition ofthe rare earth elements catalyzing mechanism is put forward.
