Abstract

Ni-W alloy coating was electrodeposited on low-carbon steel from an aqueous citrate-sulphate,while the effect of pH value on surface state, structure and corrosion resistance of the Ni-W alloy coatings was investigated. The result shows that: nanocrystalline Ni-W alloy coatings were produced when pH<7, while amorphous Ni-W alloy coatings were electrodeposited when pH>7. The hardness of Ni-W alloy coatings is correlated with the W content in the alloy coating. In contrast with low-carbon steel, Ni-W alloy coatings show much positive corrosion potential and much lower corrosion current density. Furthermore, the amorphous Ni-W alloy coating electrodeposited by pH=7.5 shows the best corrosion resistance due to the peculiar passivity of the coating in 3.5%(mass fraction) NaCl.

Key words: Ni-W alloy coating electrodeposition corrosion resistance passive electrochemical impedance spectroscopy
