  • Nickel pH adjustment method and apparatus
    Patent number: 8980068
    Abstract: An electrolytic cell for adjusting pH and replenishing nickel in a nickel plating solution of a nickel plating bath and a method of using the same is disclosed. The electrolytic cell comprises an inlet for receiving nickel plating solution from the nickel plating bath; a cooled cathode connected to a first bus bar connected to a negative terminal of a power supply; a plurality of nickel anodes capable of creating hydrogen gas on the cooled cathode when current is applied, connected to at least a second bus bar, the at least the second bus bar connected to a positive terminal of the power supply; and an outlet for returning nickel plating solution in the electrolytic cell to the nickel plating bath.
    Type: Grant
