Abstract
A method of plating steel strip with a zinc-nickel alloy in an acidic bath, comprises continuously passing the steel strip through the electrolytic plating bath under the conditions that the concentration of Ni.sup.2+ is kept at a level of 20 g/l or more and the concentration of Zn.sup.2+ at a level of 10 g/l or more and the molar ratio of Ni.sup.2+ /Zn.sup.2+ is restricted to a range of from 1.5 to 4.0 with the speed of passage of the steel strip through the electrolyte relative to the counter-current flow of the electrolyte kept at 10-200 m/min.
