    Abstract
    The effect of surface parameters on corrosion behaviour of pure zinc in sodium sulphate solution was investigated. Surface parameters were determined using a Talysurf surface analyzer, and corrosion testing was performed using the Tafel plot technique. It was found that the corrosion rate decreases linearly with increasing the grit size while the polarization resistance increases. Also, it was found that the increase in surface roughness has two connecting effects. The first leads to a decrease in corrosion potential due to a decrease in the cathodic surface area while the second leads to an increase in corrosion potential due to a decrease in the peak to valley distances of surface irregularities
