Boric acid in nickel plating solution
WebJan 1, 1996 · Boric acid prevents the electrode surface passivation on nickel reduction. Furthermore, boric acid acts as a surface agent and functions as a selective membrane … WebBoric acid acts as an overall buffer for the solution. Its effects is most noticeable in higher current density areas where it 1) Prevent burning and pitting 2) Helps to provide deposit ductility and 3) Maintain the proper Cathode efficiency. The proper concentration of boric acid minimises an increase in bath pH in the areas close to cathode.
