Abstract
PURPOSE: To obtain the captioned electrode of low hydrogen overvoltage by electroplating substrate metal base in the Fe/Co 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 Fe/Co 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 in which the total of the concentrations of ferrous ions and cobalt ions has been controlled to 0.1W2mol/l and pH to 2.5W 6.0, then the hydrogen overvoltage when it is used for water electrolytic cathode decreases considerably.
