摘要： Steel strips are electrogalvanized with a Zn-Ni alloy deposit having the desired nickel content in a consistent manner for a long time by placing separate Zn and Ni soluble anodes in a chloride plating bath comprising major proportions of ZnCl 2 and NiCl 2 in an Ni/(Zn + Ni) ratio between 0.08 and 0.20 and a total molar amount of Zn + Ni of from 1 to 4 moles per liter, and b mole per liter of KCI and a mole per liter of NH 4 Cl as shown in Fig. 8; passing a steel strip through the bath; and introducing currents to the soluble Zn and Ni anodes in a specific ratio given by equation (2).
