Abstract
726,133. Electrolytic treatment of wire. METRO-CUTANIT, Ltd. May 27, 1953 [Oct. 9, 1952], No. 14796/53. Class 41. In a method of electropolishing or otherwise removing metal from the surface of metal wire, strip or ribbon, by its treatment as an anode in an electrolytic bath, the surface of the electrolyte is covered by a layer of an insulating liquid of lower specific gravity than the electrolyte, in which layer the current connection to the wire is made. A layer 3 of insulating liquid, which may be a saturated hydrocarbon such as a saturated petroleum fraction, is arranged on top of electrolyte 2 in a vessel 1 having a cathode 7. Wire 4 is led through the electrolyte by insulated guide rolls 5 and metal roll 6, which roll 6 dips into the insulating liquid layer 3 but not into the electrolyte and supplies current to the wire. The method may be used when the electrolyte contains a component exhibiting partial solubility with respect to petroleum, such as ethanol in an aqueous solution of phosphoric and citric acids for electropolishing chromium-nickel-steel, or methanol in an electrolyte for electropolishing molybdenum wires. When the electrolyte is used at an elevated temperature, the insulating liquid may be a saturated hydrocarbon which is liquid at the working temperature but solid at room temperature.
