“软氮化”系指一般结构钢和铸铁在较低温度下进行碳氮共渗的一种热处理方法。氮化层具有高度的耐磨、耐蚀和耐疲劳性能。目前生产上多采用盐浴软氮化法。1965年以前,我国工厂软氮化盐浴都以剧毒的氰化盐为主;为了改善工人的劳动条件,1965年以后,广大职工通过试验研究,创造了无毒原料软氮化(以尿素为主)法,使软氮化工艺前进了一步。1966年,我厂试验采用了无毒原料软氮化工艺(盐浴为尿素、碳酸钠、氯化钾),用来处理产品零件如球座、蜗轮(灰铸铁)和球头丝杆、螺母(45钢)等,提高了零件
“Soft nitrocarburizing” refers to a method of heat treatment for carbonitriding common structural steels and cast iron at lower temperatures. The nitride layer has a high degree of wear resistance, corrosion resistance and fatigue resistance. At present the production of salt bath with soft nitriding method. Before 1965, the soft nitrided salt baths in our country were dominated by the highly toxic cyanide salts. In order to improve the working conditions of the workers, after 1965, the majority of workers and workers through trial and research created a soft nitriding of non-toxic raw materials Mainly) method, so that the soft nitriding process a step forward. In 1966, our factory experimented with the non-toxic raw material nitrocarburizing process (salt bath is urea, sodium carbonate, potassium chloride) to handle the product parts such as ball seat, worm gear (gray cast iron) and ball screw, nut (45 steel), etc., to improve the parts
