Electrochemical deposition and characterization of ZnFe alloys

ZnFe alloy electrochemically deposited on steel under various deposition conditions were investigated using anodic linear sweep voltammetry (ALSV) and X-ray diffraction (XRD) analysis for phase structure determination, energy dispersive X-ray (EDX) analysis for determination of chemical composition, and polarization measurements and open circuit potential measurements for determination of corrosion properties. The influence of deposition current density on the chemical composition, phase structure and corrosion stability of ZnFe alloys was studied. It was shown that deposition current density strongly affects the corrosion stability of ZnFe alloys, while ZnFe alloy electrodeposited at 4 A dm-2 exhibited the lowest corrosion rate.
