Irregular blistering on the whole workpiece, normal color of the base metal on the reverse side of the plated layer, must it be related to the alkaline copper plating additives? Not necessarily, it may be caused by the imbalance of the ratio of tank solution components.
In the production process of using chrome plating additives, we often encounter a headache, that is, the leakage of plating solution, which causes a lot of trouble to the waste water and exhaust gas treatment. So how can we avoid the leakage of plating solution in the production?
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?
