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.
In the production process of using nickel plating additives, sometimes the workpiece coating appears rough and burrs.Even if the plating solution is treated with impurities, this will happen again soon, which is very troublesome.What causes this phenomenon?
When we use alkaline zinc nickel alloy plating additive for production, sometimes the coating in the high current area of the workpiece has stripes, which will seriously affect the appearance and performance of the coating. So, how can this phenomenon occur?
