Abstract

786,418. Electrodeposition of iron-zinc alloys. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Feb. 24, 1954 [Jan. 13, 1953; Sept. 14, 1953], Nos. 999/53 and 25306/53. Class 41. Iron-zinc alloys are deposited on cathodes of iron, steel or more positive metals from a bath containing iron and zinc, an ammonium salt to prevent decreasing acidity at the cathode, a chelating agent such as an aliphatic hydroxy carboxylic acid, e.g. citric acid, to prevent precipitation of ferric hydroxide and an alkali metal chloride to inhibit anode passivation. Preferably an iron anode is used with, if desired, a subsidiary zinc anode for high zinc content alloys for which a wetting agent such as the sodium salt of sulphated straight chain higher alcohols, e.g. that sold under the Registered Trade Mark " Teepol " is added to smooth the deposit and allow use of higher cathode current densities. Sulphate baths comprising per litre ferrous and zinc sulphates in amounts ranging from 50-15 gms. Fe and 2-25 gms. Zn, giving alloy deposits containing from 6-92 per cent Zn, 118 gms. ammonium sulphate, 10 gms. potassium chloride and 0.5 gm. citric acid with 0-30 gms. " Teepol " are used at a temperature of 50‹ C. with a current density of 30-400 amps./sq. ft. With a chloride bath containing per litre 117 gms. ferrous chloride, 48 gms. zinc chloride, 30 gms. ammonium chloride, 15 gms. potassium chloride, and 0.5 gm. citric acid at pH 1.25, a bright 44 per cent Zn alloy was deposited at 50‹ C. with a current density of 750 amps./sq. ft. The first Provisional Specification refers to the use of ferrous ammonium sulphate in place of ferrous sulphate and ammonium sulphate and gives slightly different bath compositions.
