摘　　要：本文研究了室温形变和稀土元素对离子ＳＣＮ共渗过程的影响。试验结果表明室温形变对离子ＳＣＮ共渗过程和气体氮化过程的影响有着不同规律。稀土元素对离子ＳＣＮ共渗工艺具有明显的催渗作用。且发现对于合金钢的催渗效果要比碳钢大。对室温成型工件进行稀土ＳＣＮ共渗工艺处理，可有效地改善工件表面性能。In this paper the effect of room temperature deformation and rare earth elements on ion sulpo-nitrocarburizing was studied. Experiment results showed that there aredifferent characteristics between the ion sulpho-nitricarburizing and the gas nitriding for theroom temperature deformed material. A addition of rare earth elements catalyize the ionsulph-nitricarburizing process envidently. The catalyizing action on alloy steel is more thanthe carbon steel. The surface property of room temperature deformed parts are developed byion sulph-nitricarburizing process.
