Electrochemical deposition and characterization of Zn-Fe alloys
MetadataShow full item record
Zn-Fe alloy electrochemically deposited on steel under various deposition conditions were investigated using anodic linear sweep voltammetry (ALSV) and X-ray diffraction (XRD) analysis forphase 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 Zn-Fe alloys was studied. It was shown that deposition current density strongly affects the corrosion stability of Zn-Fe alloys, while Zn-Fe alloy electrodeposited at 4 A dm(-2) exhibited the lowest corrosion rate.
