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.
Electroplating plant in the face of nickel plating layer appears rough fault, often first from the nickel plating brightener to start troubleshooting, but in the actual production, the cause of roughness is a variety of reasons, such as hangers, sanding copper rods, treatment of the plating solution is not filtered thoroughly, and so on. This issue of the article we will analyze.
In the previous article, we talked about two reasons why mechanical impurities can cause rough plating when using copper pyrophosphate brighteners, in addition to the other 2 reasons why mechanical impurities can also occur. These are the introduction of anode sludge and external fallout.
When using decorative chrome additives, in order to ensure the quality of the plated layer, the plating plant should use a low ripple DC output power supply. However, in actual production, plating failures can also occur if not operated properly.
