我国应用渗硫工艺已有二十多年的历史,国外也不过三十多年,是比较年轻的一种工艺.它的出现与解决机械零件的磨损,特别是咬合磨损有密切的关系. 低温电解渗硫法是近年来才出现的一个新工艺,设备简单,处理温度低(200℃以下),处理时间短(20分钟以下),不用剧毒的氰盐,可处理钢材种类多,耐磨性好.处理温度这样低,时间这样短,单纯靠热能已不能满足反应的需要,于是就引入电能,进行电解(离子导电)处理.国外有人把包含离子导电过程的热处理称为电解热处理,干式的如离子氮化、放电硬化等,湿式的如电解
The application of sulfurizing technology in our country has been more than 20 years of history, but also more than 30 years abroad, is a relatively young technology. Its appearance and the solution to the mechanical parts wear, especially occlusal wear is closely related. Electrolytic sulphurization is a new process which has appeared in recent years. It has the advantages of simple equipment, low temperature (less than 200 ℃), short treatment time (less than 20 minutes), no toxic cyanide, Good treatment temperature is so low, the time is so short, simply rely on thermal energy has been unable to meet the needs of the reaction, so the introduction of electrical energy, the electrolysis (ion conduction) treatment Some people abroad to include the ionic conductivity of the heat treatment is heat treatment, dry Such as ion nitriding, discharge hardening, wet, such as electrolysis
