一、前言无氰液体软氮化是目前国内广泛采用的一种化学热处理工艺,它的特点是:实现了原料无毒化,操作简便,生产周期短,氮化质量稳定,处理温度较低,因而使零件的变形量极小;同时,抗蚀性能及抗咬合性能也明显提高;此外,采用该工艺无需使用特殊的氮化钢和昂贵的氰盐,可显著提高钢制零件的使用寿命,降低成本。由于该工艺所需设备简单,产
I. Introduction Non-cyanide liquid nitrocarburizing is a widely used chemical heat treatment process in China. Its features are: to achieve non-toxic raw materials, easy operation, short production cycle, stable nitriding quality and low treatment temperature So that the deformation of the parts is extremely small; the same time, corrosion resistance and anti-seizure performance is also significantly improved; In addition, the use of the process without the use of special nitriding steel and expensive cyanide can significantly improve the service life of steel parts and reduce cost. Due to the equipment required for the process is simple, production
