Abstract

Electrodepositing Co WC composite coatings from cobalt electro bath including WC particles was studied. WC particles accelerate the cathode reaction of composie electrodeposition. In alkaline solution the electrocatalytic properties of evoluting hydrogen were investigated. The results show that the properties of electrode remain superior and stable in a long term interval electrolyzing experiment.
