Abstract: : High-speed electrogalvazing have attracted increasing interest from the automobile industry and steelmakers because of it's high efficiency and excellent mechanical properties. Flow velocity of electrolyte is closely related to the coating properties especially roughness and texture. Effect of flow velocity of sulfate electrolyte electrogalvazing on morphology, roughness and crystal orientation of zinc deposit, was studied with self-made simulative gravity high-speed plating bath. The results showed that effect of flow velocity on micromorphology of zinc deposit was evident: High velocity got dense and smooth deposit, while slow velocity resulted in rough and convexoconcave one. Foremost in this study, it was found that there was linear decline of deposit roughness with the increase of flow velocity, the formula of this relationship established in this paper was: Ra=a+bv, further study on which confirmed the discipline of effect of deposit thickness and current density on deposit roughness.
