AbstractTo enhance the corrosion resistance of directional structure coating of Ni60 alloy, the directional structure composite coating of Ni60 alloy reinforced with WC was prepared on the S45C steel by the induction remelting and forced cooling method. The immersion corrosion behaviors of coatings in 10% H2SO4 solution for 168 h and its electrochemical corrosions were investigated to analyze its corrosion resistance. The results showed that WC changed the grain boundary density and grain boundary type, having important effect on corrosion resistance and corrosion mechanism of directional structure Ni60 coating. The corrosion potentials of directional structure Ni60 coating and Ni60/WC coating is -0.395 and -0.112 V, respectively. The corrosion resistance of directional structure Ni60/WC coating is better than that of the coating without WC. The corrosion mechanism of directional structure Ni60/WC coating is slight intracrystalline corrosion, while the coating without WC is the pitting corrosion and the microgalvance corrosion.
