Abstract
A process for nickel plating a cylindrically shaped hollow core mandrel suitable for chromium plating for use in an electroforming process for the production of endless seamless nickel xerographic belts, is disclosed. The process comprises providing a hollow core aluminum or aluminum alloy cylindrically shaped member and (1) anodizing this core member by using this core member as an anode in an anodizing bath where the cathode comprises lead or lead alloys and (2) nickel plating this anodized core member in a nickel electroforming bath where the core member becomes the cathode and the anode is nickel or nickel alloy. Additionally and optionally, this core member may then be (3) subjected to an acid dip bath where the core member remains for a particular length of time and, additionally, then the core member is (4) plated with chromium by placing the core member in a chromium electroplating bath with a metal anode of lead or lead alloys.
