Abstract

404,251. Electroplating. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Nov. 9, 1933, No. 31263. Convention date, Feb. 15. Addition to 385,067. [Class 41.] Aluminium or an alloy thereof is prepared for electro-plating by anodic treatment in a bath containing phosphoric acid to form an oxide film which is then reduced in an alkaline bath containing metallic compounds with simultaneous deposition of metal such as copper or brass which forms a base for further electrodeposition. The anodic bath preferably contains 1-10 per cent of phosphoric acid and is operated at 40-50‹ C. The temperature should, however, be lower for alloys having a considerable heavy metal content. The period of oxidation, the bath temperature and the concentration should be regulated to obtain a porous oxide layer. Direct or alternating current may be used. Alloys containing magnesium may be treated. Specification 394,637, is referred to.
