![عکس صفحه اول مقاله: Influence of Co2+ and Cu2+ on the phase composition of Zn–Ni alloy Influence of Co2+ and Cu2+ on the phase composition of Zn–Ni alloy](/preview/png/195467.png)
Influence of Co2+ and Cu2+ on codeposition of Zn–Ni in acetate–chloride electrolyte have been investigated by the potentiodynamic stripping and XRD methods. In our earlier work it has been determined that the quantity of the η-phase in the alloy increased with decrease in the quantity of Ni when codeposition of Zn–Ni took place in acetate–chloride electrolyte. Meanwhile, both the quantity of Ni and that of the η-phase in the alloys decreased, when Co or Cu were incorporated in the alloy. Data of XRD have shown that the quantity of γ-phase in the alloy increased with increase in the quantities of Co2+ or Cu2+ in acetate–chloride electrolyte. When concentration of [Co2+] (0.15 mol dm−3) was approximately 19 times as high as that of [Cu2+] (0.008 mol dm−3), the influence of Co2+ and that of Cu2+ on the phase composition of alloys were nearly similar.
