<p>A Zn-Ni alloy electroplating solution for obtaining Zn-Ni alloy-electroplated steel with excellent surface appearance, which contains ZnCl2 and NiCl2 as major components. In the solution, the percentage molar concentration. x(%), of Ni<2><+>/Ni<2><+> + Zn<2><+> and the concentration of chloride (at least one chloride selected from the group consisting of AlCl3, NH4AlCl4, NHcCl, KCl, NaCl, CaCL2, BaCl2, and MgCl2), y (mol/liter), are kept within the following ranges: - 0.2 x + 15.0 >/= y >/= - 0.2 + 9.0 7.0 >/= y >/= 0.2 60 >/= y >/= 10l</p> |
