AB  - Zn - Mn alloy electrodeposition on steel electrode, in electrolytes containing chloride or sulfate anions, was investigated by chronopotentiometry. Galvanostatically obtained electrodeposits were characterized by X-ray diffraction (XRD), atomic force microscopy (AFM), and atomic absorption spectrophotometry (AAS). It was found that Zn2+ and Mn2+ ion reduction occurred at higher overpotentials in sulfate bath, leading to a higher Mn content in the deposit and smaller crystallites as compared to the chloride electrolyte. AFM images of deposits revealed that with the increase in deposition current density, bigger agglomerates formed in both electrolytes, leading to higher roughness and heterogeneity of the samples. In relation to this observation, the Zn - Mn coatings were deposited at current densities of up to 80 mA cm(-2) because at higher current densities the samples from sulfate electrolyte were non adherent and dendritic. Depending on the deposition current density, the XRD patterns of the Zn - Mn deposits produced from chloride electrolyte indicated that the coatings were formed of either eta- or epsilon-Zn-Mn phase, while the coatings obtained from sulfate bath consisted of epsilon-Zn - Mn phase. The linear polarization method showed that Zn - Mn alloys deposited from sulfate electrolyte exhibited higher corrosion resistance in NaCl corrosive media.

AB  - Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy (AAS) for determination of chemical composition, anodic linear sweep voltammetry (ALSV) and X-ray diffraction (XRD) for phase structure determination, SEM and AFM for surface morphology analysis, and polarization measurements for determination of corrosion properties. The influence of deposition current density and composition of deposition solution on the phase structure, morphology and corrosion properties of Zn-Co alloys were studied. The plating baths used were with low metal concentration, free of additives and deposition was carried out at room temperature, since the aim of the work was to investigate only the influence of different deposition current densities using economically favorable deposition parameters. It was shown that the ratio of cobalt to zinc ions in the plating bath strongly affects the chemical content and phase structure, as well as the morphology and corrosion stability, of Zn-Co alloys. The single-phased Zn-Co alloys showed the best corrosion stability. The alloys deposited at the highest current density from plating bath with the lower ratio of cobalt to zinc ions, as well as the one deposited at the intermediate current density from bath with higher ratio of cobalt to zinc ions, exhibited the lowest corrosion rates. It was also shown that the deposit having smaller crystallite grains (obtained at higher current density), among two alloy deposits having the same chemical content and phase structure, yielded lower corrosion rate.
