| Abstract: | WC/Co composite powders prepared by electroless plating were coated on 2Cr13 stainless steel by laser cladding. The composition, morphology, microstructure and performance of the WC/Co composite coating were studied. The results show that the WC/Co composite powders contain about 17.23wt% of Co.It is found that the composite coating is metallurgically bonded to the substrate.The coating consists of three zones: melting zone, bonding zone and heat affected zone of the substrate. The micro-hardness of the coating reaches 1200HV_ 0.1 . |
