摘　　要：对离子氮化的稀土硅铁催渗进行了工艺试验和耐磨性对比试验。结果表明,稀土硅铁对离子氮化具有显著的催渗作用,可使氮化时间缩短一半,和普通离子氮化比较,与硬材料配磨,耐磨性相近,与软材料配磨,催渗后抗粘附能力有所提高。Process experiment and wearing comparison experiment havebeen made for reareath-ferrosilicon catalysis of ionic-nitriding. The experimentresults show that rear-eath-ferrosilicon can produce substantial effect of catalysisionic-nitriding and half a time for nitriding may be reduced. By comparison withnormal ionic-nitriding, wearability is nearly the same if it is weared with hardermaterials. And adhesion resistance increases if it is weared with softer matearialsafter catalysis.
