Abstract:
1. A system for electroplating a workpiece, the workpiece having an interior with a surface, comprising: an anode having an axis configured to be located in the interior of the workpiece adjacent to the surface and immersed in an electroplating fluid solution; a centralizer mounted to the anode for centralizing the anode within the interior of the workpiece, the centralizer being electrically non-conductive; a seal mounted to the anode for retaining the electroplating fluid solution in contact with the anode and the surface of the workpiece, wherein the seal is in sealing engagement with the surface of the workpiece while the anode and seal move through the interior of the workpiece; a cable wrapped around a drum reel and operatively coupled to the anode, centralizer, and seal for moving the anode, centralizer, and seal through the interior at a controlled rate; an electrical power supply electrically connected via a first wire leading to the anode and a second wire to the workpiece for supplying a voltage to the anode, through the electroplating fluid solution, and to the workpiece to plate the surface with the electroplating fluid solution; and wherein the wire is spaced apart from the cable.
