1,132,696. Electrolytic deposition of aluminium. NIPPON KOKAN K.K. Nov.12, 1965 [Nov.13, 1964; Feb.24, 1965(2)], No.48121/65. Heading C7B. In a process for electrolytically coating metallic surfaces with aluminium in a molten salt bath containing aluminium chloride, hydrogen ions are supplied to the reacting zone between the metallic surface and the molten salts. The hydrogen ions may be supplied by coating the metallic surface with a film of a supply source e.g. with an aqueous film or with a film of hygroscopic inorganic or organic material, for instance in aqueous solution; by introducing hydrogen and/or hydrogen chloride gas in the form of small bubbles into the electrolyte or by cathodic treatment of the metal surface deposition of aluminium thereon, in an acid bath containing Pb, Sn, Ti, Zn, Bi, Cr or Cd. |
