  • Publication number: 20020182337
    Abstract: A process for mechanical plating zinc alloys onto metal substrates is disclosed. The process is particularly suited to plating zinc-aluminium or zinc-manganese alloys onto aluminium or magnesium substrates. The zinc alloy particles are immersion coated with tin prior to plating upon the metal substrate. Fluoride ions are preferably added to the plating media to increase plating efficiency, particularly when zinc aluminium alloys are being plated.
