用尿素和纯碱为主的液体软氮化,因盐浴中含有一定量的氰根,引起不少争论,但由于其设备简单、材料费用较低、处理温度较低、能耗少、质量能够保证,在还没有条件上气体碳氮共渗的工厂,仍然是一项可行的工艺。 Due to its simple equipment, lower material cost, lower processing temperature, less energy consumption and good quality, the soft nitriding of liquid with urea and soda ash as a result of the salt bath containing a certain amount of cyanide has caused much controversy It is still a viable process to make sure that plants that have gas-carbonitriding on conditions are not yet available.
