Synergistic Effect of Tobacco and Sugarcane Extracts on the Surface Morphology of Electrodeposited Zinc on Mild Steel

摘要

Experimental investigations have been performed to determine the synergistic effect of nicotianatobaccum (tobacco) and saccharum officinarum (sugarcane) extract additives on the electrodepositionof zinc on mild steel in acid chloride solution. The experiments were performed under different platingtime, different additive concentrations and fixed pH conditions. Zinc electrodeposition on mild steelwas performed using a DC supply at defined operating parameters. The surface of the plated steelwas examined using scanning electron microscopy (SEM); and Energy Dispersive Spectroscopy (EDS)for surface elemental composition analysis. Different surface characteristics were obtained dependingupon the concentration of the additive and the plating time. The corrosion resistance of the platedsurface was also determined by gravimetric method. The quality of the electroplating of zinc was goodas indicated by the microstructural morphology of the plated surface. The electrodeposition processwas sensitive to changes in additive concentration and plating time. Any variation in the platingparameter produced an entirely new and different surface crystal morphology.
