Abstract

1,182,614. Electrolytically producing a ferric oxide film. CANADIAN PATENTS & DEVELOPMENT Ltd. June 1, 1967 [June 20, 1966], No. 25367/67. Heading C7B. A fine-grained, compact ferric oxide film is electrolytically produced on an anode immersed in a bath containing ferrous iron in solution, the anode potential being controlled so that the potential difference between the anode and a calomel reference electrode is maintained in the range of -200 to +800 millivolts. For example, the ferrous iron may be in a deaerated borate buffer solution of pH 8 in which case the films contain some borate. The films, e. g. 10 to 10, 000 A thick, may be deposited on any conductive material, e.g. Fe, Pt, Zn or Ag, or on non-conductors coated, e.g. by evaporation or sputtering, with conducting material such as Fe or other metal. Such non-conductors may be wood, paper, cloth or polymeric material, e. g. plastic tape. The films may be used to enhance the protection given by protective oxide films on iron, to form coloured films on iron or other metals by controlling the thickness to give various interference colours and to form thin magnetic or semi-conductor films. Transparent coatings may be applied over a coloured film layer. The properties of the oxide can be modified by further anodic oxidation in the absence of Fe<SP>++</SP>. The oxide can be heat treated to form Fe 3 O 4 or y -Fe 2 O 3 .
