低温电解渗硫是七十年代初发展起来的新工艺,是一种以减小摩擦系数、增加抗咬合能力为目的的表面化学热处理方法。许多磨损和咬合上的问题(除磨粒磨损外),都可以通过这种新型的表面处理得到显著改善。因此,它对机械制造业具有重大的意义。多年来,在国内因对该工艺的原理尚缺乏较深入的探索,所以工艺过程一直得不到稳定。近来,我们对此进行了一些研究,取得一定成效,现将结果作如下论述。一、实验方法试验用的渗硫装置如图1所示,工件浸入坩锅3中的熔盐里,和可变直流电源2的正极相联,坩锅与负极相接。变压器5接发热体
Low temperature electrolytic sulfurization is a new technology developed in the early seventies. It is a surface chemical heat treatment method aimed at reducing the friction coefficient and increasing the anti-seizure ability. Many problems with wear and bite (except abrasive wear) can be significantly improved with this new surface finish. Therefore, it is of great significance to the machinery manufacturing industry. Over the years, due to the lack of in-depth exploration of the principle of the process in the country, the process has not been stable. Recently, we conducted some research on this and achieved some results. We will now discuss the results as follows. First, the experimental method Sulphurizing device used in the experiment shown in Figure 1, the workpiece immersed in the molten salt in the crucible 3, and variable DC power supply 2 is connected to the cathode, the crucible and the negative phase.
