Abstract: The influence of the variation of the metallic ions concentrations on the electrodeposition of Zn-Ni alloys on a copper substrate was studied evaluating the Faradaic efficiency. It was used a 22 factorial design, with 3 central points. So, fixing the electric current density in 12.5 mA/cm2, the variables were the concentrations of zinc and nickel. The electrolytic bath was composed by ZnSO4 and NiSO4, salts that were source of zinc and nickel, respectively, ammonium citrate as a complexing agent and sodium borate as an amorphising. The alloys showed good performance at room temperature and the Faradaic efficiency reached 95%. The concentration of zinc was more influential on the deposition efficiency than the concentration of nickel
