In the production process of using alkaline zinc plating brightener, sometimes the deposition rate of the zinc coating on the workpiece is relatively slow, which affects the production efficiency.So what factors will affect the deposition rate of the zinc coating on the workpiece?
We all know that in the process of using hard chrome plating additives, many workpieces have strict requirements for the uniformity of hard chrome coating thickness.Generally, the dispersion performance of chrome plating solution is poor. For workpieces with large area, the thicker the chrome layer is deposited, the more uneven the distribution of the coating will be due to the longer plating time and higher current during hard chromium plating.However, sometimes the uneven thickness of the workpiece coating is related to the position of the anode plate.
In the production process of using nickel plating brightener, white fog appeared on the surface of the nickel plating layer of the workpiece, especially on the large area of the workpiece. What is the reason?
