This paper describes the use of electrogalvanized steel to enhance the corrosion resistance of automobile body panels in the forming of sheet steel. The zinc coating structure and morphology, as influenced by electrolytic and hydrodynamic conditions during electrodeposition, can influence the drawing character of electrogalvanized sheet. Sheet steel samples plated with zinc deposits exhibiting 1) strong basal (0001) plane and 2) strong pyramidal plane (101x) orientation were prepared. Sheet metal forming properties, including cup deformation and drawbead performance, were related to deposit morphology and structure. The results were compared to those for commercial electogalvanized product.
