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?
In the production process of using acid tinning brightener, sometimes pinholes and streaks appear on the surface of the workpiece coating. What is the reason?
In the production process of using hard chrome additive, to obtain a hard chromium coating with a certain gloss, and the coating needs to have high hardness, good wear resistance and good adhesion, which operating points should be paid attention to?
In the process of using sulfate tin plating brightener, some large areas of workpieces have white spots on the coating around the seam, which seriously affects the appearance and performance of the workpieces.What causes this phenomenon?
