Abstract
893,370. Coating metals electrophoretically. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 2, 1960 [March 9, 1959], No. 8102/59. Class 41. Metal bodies, e.g. valve electrodes, are coated with an insulating layer mainly alumina, by electrophoretic deposition from a suspension of alumina in aqueous alcohol which contains aluminium acetate and magnesium nitrate as activators. Finely-divided silica may also be present. The coated element is then dried and heat-sintered. The coating may be in dimpled, smooth, or loosely adherent form by adjusting the ratio of the two activating salts added. Specification 847,019 is referred to.
