摘      要：WC-Co reinforced C276 alloy composite coatings are fabricated on Q235 steel by laser melting *** microstructure,hardness,wear performance,and electrochemical corrosion behavior of composite coating are *** results show that WC-Co particles are mostly uniformly distributed in the coating and provide favorable conditions for heterogeneous *** microstructure of C276/WC-Co composite coatings is composed of γ-Ni solid solution dendrites and MoNi solid solution *** WC-Co particles can effectively improve the hardness and wear resistance of C276 *** average hardness of the composite coating containing 10-wt% WC-Co(447 HV_(0.2)) are 1.26 times higher than that of the C276 alloy(356 HV_(0.2)).The wear rate of composite coating containing 10-wt% WC-Co(6.95 ×10^(-3) mg/m) is just 3.5% of that of C276 coating(196.23 × 10^(-3) mg/m).However,comparing with Hastelloy C276,the corrosion resistance of C276/WC-Co composite coating decreases.
