Abstract

PURPOSE: To obtain the captioned electfode of low hydrogen overvoltage by electroplating substrate metal base in the cobalt plating bath containing flocculants under the specific conditions.
CONSTITUTION: If substrate metal base composed of iron, stainless steel, nickel or platinum-group metals is electroplated in the cobalt plating bath which contains macromolecular polysaccharides (derivatives) such as starch and dextrin, macromolecular flocculants such as poly(2-diethyl aminoethyl methacrylate) or inorganic flocculants such as chromium sulfate and whose cobalt ion concentration has been controlled to 0.3W1mol/l and pH to 2.5W6.0, then the hydrogen overvoltage when it is used for the cathode for water electrolysis decreases considerably.
