刀具渗硫就是刀具表面飽和一层硫,利用硫化物的没有咬合性能,以及可焊性差和减少摩擦系数、增加滑潤的特性,来提高切削刀具的使用寿命。它是一种先进的强化刀具表面的工艺。固体的、液体的和气体的渗硫已在各厂用得很广了。我們在学习兄弟厂經驗的基础上,大胆进行电解渗硫試驗,取得了良好的效果,并准备正式用在生产上。我們对两类刀具进行渗硫試驗;一类是18銑刀,一类是18車刀头。电解渗硫过程是:
Sulphurizing is the tool surface saturated with a layer of sulfur, the use of sulfide does not bite properties, as well as poor weldability and reduce the friction coefficient, increase the lubricating properties, to improve the life of cutting tools. It is an advanced technology to enhance the surface of the tool. Solid, liquid and gaseous sulfur infiltration has been widely used in various plants. Based on the experience of our brother factory, we boldly carried out the electrolytic sulfurization test and achieved good results. We are ready to formally use it for production. We carry out the sulfurizing test on two kinds of tools; one is 18 cutter, one is 18 cutter head. Electrolytic sulfur infiltration process is:
