前言软氮化热处理是化学热处理的一种,它不仅能提高零件的耐磨损耐疲劳、抗胶合、抗擦伤的性能,而且还具有不受钢种的限制,处理时间短,温度低和变形小等优点。这些性能的改善和工艺上特点对齿轮来讲,是非常适合和特别需要的,因而,也引起了我们对采用软氮化处理来提高齿轮寿命的试验研究。用尿素热分解气体软氮化是近年来试验成功的一种无公害,生产方便的软氮化新工艺,
Introduction Soft nitriding heat treatment is a kind of chemical heat treatment, it can not only improve the wear-resistant parts of the fatigue resistance, anti-gluing, anti-abrasion performance, but also without the restrictions of steel species, the treatment time is short, low temperature and Small deformation and other advantages. These improvements in performance and process characteristics are very suitable and particularly desirable for gears, and therefore have led to our experimentation with soft nitriding to improve gear life. With the thermal decomposition of urea gas nitriding is successful in recent years, a pollution-free, easy production of soft nitriding new technology,
