We all know that in the production process using hard chrome additives, the workpiece can obtain a hard chrome coating with good brightness, high hardness, wear resistance and corrosion resistance. However, sometimes the hardness of the hard chrome plating of the workpiece will be low, resulting in the workpiece can not meet the requirements of machining, what is the reason for this?
As we all know, in the production process of using chrome plating additives, in order to make the workpiece to obtain a good quality of chrome plating layer, what are the basic requirements for hangers?
What is the purpose of ammonia when using a copper pyrophosphate brightener? How to control its content? Let's analyze it in this issue.
In the application production of alkaline copper plating brightener, why the top layer of the workpiece in the row above the hangers appears to blister, and the base metal shows small brown circles and gray-brown stains? In fact, it is possible that the plating solution is contaminated.
In the process of using acid galvanizing brightener, there are some plating plant plating solution is easy to produce floating oil, is floating in the plating liquid surface of the oil, what to do?
Why do fine pockmarks appear on the coating in the production process using pyrophosphate copper plating additives? It might be caused by the turbidity of the bath solution. Then why does the bath solution become turbid? Overall, there are three reasons.
