When we use the trivalent chromium color zinc passivation solution to produce, sometimes the corrosion resistance of the workpiece is poor and cannot meet the customer's requirements. What should we do?
During the application of medium-phosphorus electroless nickel plating solution, sometimes pinholes appear in the electroless nickel coating of the workpiece. What is going on?
In the production process of using alkaline zinc plating brightener, sometimes the low area of the workpiece will turn black, what should I do?
In the production process of using acid zinc plating brightener, what is the reason for the blistering phenomenon of poor adhesion of the galvanized layer of the workpiece?
In the production process of using medium-phosphorus electroless nickel plating solution, the workpiece cannot be deposited with a nickel layer, which will seriously affect the production progress. So what should we do in this situation?
In the production process of using nickel plating brightener, we sometimes find that the iron ions in the plating solution are relatively high,The brightness of the produced workpiece is relatively poor, and it is prone to yellowing and whitening,And after a few days of hydrogen peroxide treatment, this phenomenon appeared again. What is the reason?
