In the process of using hard chromium additive, the workpiece coating is prone to pinhole phenomenon, which will affect the appearance quality and production efficiency of the workpiece.What causes this?
In the process of using alkaline zinc-nickel alloy additives, sometimes the coating will be rough, which affects the coating quality and the effect after passivation. What is the reason?
When we use electroless nickel plating solution for production, because most of the reducing agents used are hypophosphite, phosphite ions will inevitably be generated in the plating solution.owever, when the concentration of phosphite is high, it will affect the deposition rate of chemical nickel. What range should the concentration of phosphite in the bath be controlled?
In the process of using barrel nickel plating brightener, sometimes the coating of the workpiece will be black and foggy, which seriously affects the quality of the coating.So what factors will affect the quality of the coating?
In the production process of using electroless nickel plating solution, sometimes the workpiece always has pits on the upward side. What is the reason?
When we use electroless nickel plating solution, in theory, the workpiece as long as immersed in the plating solution at any position can obtain uniform coating.In the production process, the workpiece in the hole, slot, slot and other positions can not get good coating, mostly to deep hole, blind hole or through hole.
