Zn-Ni alloys electrochemically deposited on steel under various deposi- tion conditions were investigated. The alloys were deposited on a rotating disc elec- trode and on a steel panel from chloride solutions by direct and reverse current. The influence of reverse plating variables (cathodic and anodic current densities and their time duration) on the composition, phase structure and corrosion properties were investigated. The chemical content and phase composition affect the antico- rrosive properties of Zn-Ni alloys during exposure to a corrosive agent (3 % NaCl solution). It was shown that the Zn-Ni alloy electrodeposited by reverse current with af ull periodT =1sa ndr = 0.2 exhibits the best corrosion properties of all the inves- tigated alloys deposited by reverse current.
