Description
Summary:In the present work, WC/Co coatings were obtained by electro-thermal explosion directional spraying technology. The performances including microstructure, elements distribution, hardness, elastic modulus and wear resistance of the coatings were investigated by means of SEM, EDAX, nano-indentation test, friction and wear test, respectively. Results show that WC/Co coatings are characterized by compact construction, good bond, high hardness and elastic modulus. The WC/Co coatings also have outstanding wear resistance.
