Improving reliability and service life of industrial products via composite electrochemical coatings

Abstract

The paper considers a method for obtaining hard, wear-resistant composite electrochemical tungsten carbide-cobalt (WC-Co) coatings with high adhesive strength. Such coatings are used to enhance surface hardness and wear resistance of parts and tooling. It is challenging to obtain hard, wear-resistant coatings on the surface of industrial parts and tooling. It is proposed to use an eco-friendly cobalt electrolyte with tungsten carbide additive for the electrodeposition of composite electrochemical coatings. The electrodeposition technique provides high output and quality of the applied coating with the ability to control its thickness.
