摘要：
This work presents the rapid electrodeposition of Fe-Ni alloy foils from chloride baths containing trivalent iron ions at a low pH (<0.0). The effect of the concentration of Ni2+ ions on the content, surface morphology, crystal structure, and tensile property of Fe-Ni alloys is studied in detail. The results show that the co-deposition of Fe and Ni is controlled by the adsorption of divalent nickel species at low current density and the ionic diffusion at high current density. The current density of preparing smooth and flexible Fe-Ni alloy foils is increased by increasing the concentration of Ni2+ ions, consequently the deposition rate of Fe-Ni alloy foils is increased. For example, at 0.6 M Ni2+ ions, the current density can be applied at 50 A.dm(-2), along with a high deposition rate of similar to 288 mu m.h(-1).
