长期来我厂在解决局部渗碳的问题上一直是采用镀铜法。面对这些烦琐的工艺,我们在厂、车间领导的大力支持下,经过了反复试验终于找到了用涂料的方法来解决局部渗碳的问题。目前已应用于我厂的工具生产上,获得了满意的效果。现把最好的三种配方介绍如下:配方一:氧化铜6份+氧化银3份+滑石粉0.5份,加适量水玻璃调成较稠状。配方二:氧化银1份+氧化铜3份,加适量水玻璃调成较稠状。 Long-term plant to solve the problem of partial carburizing has been the use of copper plating method. In the face of these cumbersome processes, with the strong support from the factory and workshop leaders, we have finally found the solution to the problem of partial carburization by means of trial and error. Has been applied to the production of our factory tools, and achieved satisfactory results. The best of the three formulations are introduced below: Formulation 1: 6 parts of copper oxide + 3 parts of silver oxide + 0.5 parts of talc, add appropriate amount of water glass into thicker. Formula two: 1 silver oxide + 3 parts of copper oxide, add appropriate amount of water glass into thicker.
