Zinc coatings were deposited from sulfate bath containing 10 and 100 ppm Sn 2+ on mechanically and electrolytically polished low carbon steel substrate. The current densities used were 10, 100, 200 and 400 mA/cm 2 . Cyclic Voltametery and cathodic sweep results showed that hydrogen evolution rate on electrolytically polished surface is more than that on mechanically polished surface in the presence of 10 and 100 ppm Sn 2+ . Hydrogen evolution rate on steel substrate and Zn electrodeposition overpotential with 100 ppm Sn 2+ are more than those with 10 ppm Sn 2+ . Besides this, Zn reduction with 10 ppm Sn 2+ is easier. Correlation between nucleation modes of deposits in different conditions and Scharifker model was studied. Calculation of surface diffusion coefficient of Zn ions in 10 ppm Sn 2+ contained bath by Scharifker equations showed that surface diffusion of Zn ions on electrolytic polished surface in 100 and 200 mA/cm 2 is about 35 and 31 times greater than that on mechanically polished surface respectively. In addition, increasing the current density increases surface diffusion coefficient of Zn 2+ ions on both mechanically and electrolytically polished surfaces. Coatings texture calculation with X-ray diffraction patterns revealed that {00.2} basal plane in 100, 200 and 400 mA/cm 2 current densities and low angle pyramidal plane in 10 mA/cm 2 are main texture component in coatings obtained from bath containing 10 ppm Sn 2+ on electrolytically polished surface. Pyramidal texture component in 10, 100 and 200 mA/cm 2 current densities and {00.2} basal plane in 400 mA/cm 2 are main texture component in coatings obtained from bath containing 10 ppm Sn 2+ on mechanically polished surface. {00.2} basal plane and {11.4}, {10.2}, {10.3}, {10.4} and {10.5} pyramidal planes are texture components in coatings obtained from 100 ppm Sn 2+ contained bath on both mechanically and electrolytically polished surfaces and high angle pyramidal plane intensity increases with increasing current density. Tafel polarization test results in deaerated 0.5%wt NaCl solution revealed that anodic branches are partially same but cathodic branches are very different. Potentiostatic tests in -1000 mV anodic potential and -1350 mV cathodic potential revealed that crystallographic orientations difference is effective on hydrogen evolution rate and has no effect on Zn dissolution rate. Comparison of correlation between coatings texture and morphology with corrosion properties revealed that coatings texture cannot be the determining parameter on corrosion resistance. Further analysis revealed that corrosion properties must be related to planes exposed to solution, porosity and effective surface.
