Abstract
PURPOSE: To obtain the title cathode with high film adherence which cathode is applicable to cathode substrates of various shapes and capable of reducing hydrogen overvoltage remarkably by forming a special iron electroplated layer contg. a flocculant on a substrate metal.
CONSTITUTION: At least part of a cathode substrate metal base made of iron, stainless steel, Ni or platinum group metal is plated with iron in an iron plating bath contg. a flocculant such as high molecular polysaccharides, e.g. starch or dextrin to manufacture a cathode for electrolysis of an aq. soln. of an alkali metal halide. The bath includes a usual ferrous chloride bath, iron borofluoride bath, NH+-free ferrous sulfate bath and mixed bath. It is required to maintain the bath at pH2.5<pH<6.0. The ferrous ion concn. in the bath is 0.1W1.7, esp. 0.5W1.5 mols/l. The plating is pref. carried out while stirring the bath with a nonoxidizing gas such an N2 gas in order to prevent oxidation of ferrous ions.
