Abstract

599,707. Electrodeposition of metals. POOR & CO. July 24, 1945, No. 18971. Convention date, Sept. 27, 1944. [Class 41] The cathode in a plating bath is subjected to an alternating current superimposed on a direct current so that the combined current is an asymmetric alternating current in which the negative peak value is between the limits of zero and minus two-thirds of the positive peak value. As shown, an anode 2 comprising one or more electrodes and a cathode 3 are in a circuit containing a rheostat 9, a low voltage direct current generator 8 and the secondary 4 of a transformer 5. The primary 6 is connected through a regulating auto-transformer 7 to a source of alternating current. The process is described in connection with the electrodeposition of antimony on a steel or other surface, employing antimony trioxide in a bath of hydrochloric acid. The electrolyte also contains arsenic trioxide, metallic selenium as an oxidizing agent and lauryl sulphate as a surface tension reducing agent. The process may also be applied to an alkaline plating bath containing potassium carbonate and antimony sulphide. In another example, a plating bath containing sodium arsenate and potassium cyanide is used. The process may be used in the deposition of metals including zinc, cadmium, tin, copper, bismuth, cerium, lanthanum, thorium, nickel, cobalt and manganese.
