Abstract
PURPOSE: To improve the durability of electrode, by using the cathode provided the first covering layer by sprayig iron group metal on the substrate of the iron group metal and moreover, providing the second covering layer on the above layer by platinum group metal or its oxide, at the time of electrolyzing water or alkali metal halogenide.
CONSTITUTION: Iron, soft steel or stainless steel, etc. are used for iron group metal substrate and its shape is able to use any of plate-shaped, rod-shaped or wire netlike. Grit blast or sand blast treatment is carried out on the surface of the substrate. Nickel or iron group metal is used for spraying metal and flame spraying or plasma spraying is carried out in powder or wire state. Thickness of the first covering layer is 300W1,000 microns. Platinum group metals, such as platinum, rhodium, iridium and platinum group metal compounds, such as platinic acid chloride, platinic acid ammonium chloride, platinous acid potassium, platinic acid potassium etc., are used for the formation of the second covering layer.
