氮化处理工艺因温度低,工件变形小,能提高工件表面的硬度、耐磨性和疲劳强度,故在工业生产中得到广泛应用。对于重载零件,常常进行渗碳处理,但如采用深层氮化代替,它也能在大负荷下安全可靠地运行,而且可以减小变形,简化加工工序。氮化虽有以上优点,但当进行深层氮化处理时,氮化周期太长,是氮化工艺的一 Nitriding process due to low temperature, the workpiece deformation is small, can improve the surface hardness, wear resistance and fatigue strength, it is widely used in industrial production. For heavily loaded parts, carburizing is often performed, but with deep nitriding, it operates safely and reliably under heavy loads and reduces distortion and simplifies machining. Although the above advantages of nitriding, but when the deep nitriding process, the nitriding cycle is too long, is a nitriding process
