用甲醇低温裂解气+氮气制备成成分相当于吸热式的气氛,再加氨气,进行风冷发动机七种零件的软氮化处理。结果表明,处理后零件的各项性能均达到了西德道依茨公司标准(KHD标准),为软氮化工艺提供了新的气源,该气源并可用于碳氮共渗。 Methanol pyrolysis gas + nitrogen gas is prepared into a composition corresponding to the endothermic atmosphere, coupled with ammonia, air-cooled engine seven parts of the soft nitriding. The results show that the performance of the treated parts meets the West German standard (KHD standard), which provides a new gas source for the nitrocarburizing process and can be used for carbonitriding.
