Abstract

Compositionally modulated multilayer (CMM) coatings Zn-Ni alloy were produced on steel surface by electrochemical deposition from the acetate electrolytic bath under various cyclic cathode current densities. Multilayer deposition and its composition at different cyclic current density range are related to the corrosion resistance properties of the deposit. Anti-corrosion properties were evaluated by potentiodynamic Tafel extrapolation method in 3.5% NaCl results showed that zinc-nickel computationally modulated multilayered alloy coatings have enhanced corrosion resistant than monolayer of binary Zn-Ni alloy deposits. The Zn-Ni multilayer alloy deposit with 120 sublayers obtained at cyclic cathode current density at 2.0-3.0 A/dm2 shows enhanced corrosion resistance and XRD confirm the presence of high intensity ?- phase.
