Development of the high-speed alkaline Zn plating system.
Generally, alkali zinc plating bath is slower plating speed compared with acid zinc plating bath. If we can speed up plating, it's considered that cost reduction and environmental concerns, etc. desired recently may be solve the problems. First we synthesize additives that not allow plating film to be defective like burning or blister current density is higher though. Secondly, we developed a special catalyst having low hydrogen overvoltage and realized a dissolution system to supply sufficient zinc. The zinc supply speed is 10 to 20 times compared with the conventional one using iron and nickel alloy. By utilizing this system combined the above additive and catalyst can contribute to improvement of productivity, downsizing a dissolution facility, reducing amount of plating solution, etc.
