It is believed that the plating speed of alkaline electroless nickel plating solution is very low and not used practically. Various alkaline electroless nickel plating solutions were examined theoritically and experimentally and the plating speed in alkaline (pH 9.0) plating solution composed of 0.1M-nickel chloride, 0.2M-sodium citrate, 0.1M-borax and 0.1M-sodium hypophosphite, was found to be as high as that of the acid (pH 4.5) plating solution used practically, which shows that such alkaline plating solution is also promising.
