铁素体的软氮化工艺现在被广泛用来改善低碳钢的摩擦性能和疲劳性能。已有报道,除显著改善耐磨性以外,疲劳强度可增加到140％。气体软氮化是作为代替有毒的盐浴软氮化而发展起来的。典型情况是在570℃处理
Ferrite nitrocarburizing process is now widely used to improve the low carbon steel friction and fatigue properties. It has been reported that in addition to significantly improving wear resistance, the fatigue strength can be increased up to 140%. Gas nitrocarburizing is developed as a soft nitriding instead of a toxic salt bath. Typically it is treated at 570 ° C
