Abstract (en)
[origin: WO2004108995A1] An apparatus (12) for applying a zinc or zinc-alloy electroplate to a workpiece comprises an electroplating bath (16) having a pH more than about 14. The electroplating bath includes zinc ions and an additive. A cathode workpiece (18) is in the bath. An anode assembly (20) contacts the bath. The anode assembly includes an anolyte and an insoluble metal anode in the anolyte. The additive is capable of electrolytically breaking down upon contact with the anode. The anode assembly inhibits the electrolytic breakdown of the additive.
