<p>ZINC ANODE BENEFACTION - This invention relates to an improved method of electroplating zinc while simultaneously effecting enhanced anode corrosion characteristics, which comprises passing current from a zinc anode to a metal cathode through a plating solution containing at least one organic brightener, a chloride-containing salt providing chloride anions and boric acid as a buffer in the absence of ammonium cations, chelating agents, and complexing agents for a time period sufficient to deposit a zinc electrodeposit upon said cathode; the improvement consisting of the current passing through an aqueous acidic bath composition containing zinc sulfamate providing zinc cations for electroplating zinc. - i</p> |
