Abstract
356,443. Electroplating. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, Liverpool, VELARDE, C. A., 16, Withert Avenue, Higher Bebington, Cheshire, and SMITH, E., 12, Prospect Vale, Fairfield, Liverpool. Aug. 20, 1930, No. 24914. [Class 41.] Aluminium or an alloy thereof is electroplated with another metal and heated to 475-525‹ C. to promote the adherence of the coating. In an example, an aluminium article is polished to remove any pin-holes or scratches and then dipped into a boiling strong potash solution until gas is liberated. It is then washed and dipped in acid. It is again washed and plated with nickel, then washed and dried and subjected to the heat treatment for 10-15 minutes. It may then be polished. The nickel bath may consist of 3¢ lbs. nickel sulphate, 1 oz. nickel chloride and 3 ozs. sodium chloride to 1 gallon of water. The current density is preferably 15 amps. per sq. ft. at 1À5 volts, the temperature 80‹ F., and the pH value 5À4. The article may be given a further coating of copper, chromium or other metal.
