钢铁零件表面渗硫可以显著地提高其耐磨性和抗咬合性。可是以往的渗硫工艺温度高,时间长,介质中多含有剧毒氰化物,使它在实际应用中受到了限制,在大跃进的年代里我国工人阶级为了提高刀具的使用寿命提出了低温电解渗硫的新工艺使渗硫温度由500～600℃降低到100～200℃,渗硫时间由1～3小时降低到10～20分钟,更重要的是不用剧毒氰盐介质。文化大
Sulfurizing the surface of steel parts can significantly improve its wear resistance and seizure resistance. However, in the past, the process of sulfur infiltration with high temperature and long time contained many toxic cyanides in the medium, which restricted it in practical application. In the era of the Great Leap Forward, in order to improve the service life of the tool, the working class in our country proposed the low-temperature electrolysis Sulfur infiltration of the new technology so that the infiltration sulfur temperature from 500 ~ 600 ℃ to 100 ~ 200 ℃, infiltration time from 1 to 3 hours to 10 to 20 minutes, more importantly, do not use toxic cyanide medium.
