  • Patent number: 4501647
    Abstract: The invention relates to a method of electroplating metal, primarily chromium, onto a workpiece connected as a cathode in a current circuit, the workpiece being fed through an electrolyte bath past the anode of the current circuit. Prior to moving the workpiece past the anode, the workpiece is moved past a member in the electrolyte bath which is generally parallel to the direction of movement of the workpiece and which is generally closer to the workpiece than the anode. This member controls the current density between the member and the workpiece, causing the workpiece to be etched as it passes the member.
