Abstract
A zinc-nickel alloy is electrodeposited on a steel strip by passing the steel strip through a stream of sulfuric acid-containing plating solution which contains 2-3 mol/liter in total of Zn.sup.2+, Ni.sup.2+, H.sup.+, and SO.sub.4.sup.2- ions and at least 0.1 mol/liter of Na.sup.+, K.sup.+, or NH.sub.4.sup.+ ion at pH 1 to 2.5, feeding the solution at a flow speed of at least 1 m/sec., and applying electricity between the strip and an anode in the solution such that the current density between the strip and the anode at the outlet of the solution is lower than that at the inlet of the solution. The anode may preferably be divided into a plurality of segments. This process may be carried out by use of a radial or horizontal cell.
