In the process of using nickel plating brightener, due to the crystallization of nickel metal has a certain deformation or heterogeneous impurity, it will produce a certain amount of internal stress in the plating layer. When the internal stress of the nickel layer is large, the hardness of the plating layer will be larger, but easy to peel, crack or poor ductility. So, what are the factors related to the internal stress of the nickel layer?
When alkaline copper plating brightener is used in plating plant, the contamination of plating solution by hexavalent chromium will also cause poor bonding of plating layer, which we will analyze in this article.
In the use of electroless nickel solution, some customers will require the workpiece to have high hardness and also have high corrosion resistance, how to operate?
Why does the coating peel off when using hard chrome additives?
What causes a plating plant to use decorative chrome additives where the tank voltage is high but no bubbles precipitate on the cathode? In our experience, there are several possibilities, namely poor conductive contacts, too small anode area, and a faulty chrome plating power supply. So why is the chrome power supply so important? And how do we choose the right one? The articles in this issue give you all the answers.
When using acid copper plating brightener, when the plating bath is deep and static plating with cathode movement is used, large solid particles will gradually sink to the bottom of the bath, which seems to have little effect, but it will bring about a series of problems as below.
