Abstract

The plating quality effect of manihot esculenta c. (cassava) leaf extract as addition agent on the electroplating of zinc on mild steel in acid chloride solution was investigated in the laboratory. The experiments were performed using different extract additive concentrations, different plating time and fixed pH conditions. A DC – supply at defined operating parameters was used to perform the electroplating of zinc on mild steel. The surface of the plated steel was examined using a scanning electron microscope (SEM) equipped with Energy Dispersive Spectroscopy (EDS). This was used to examine the surface of the plated steel for surface morphology and for surface elemental composition analysis. Distinct variable surface characteristics were obtained depending upon the concentration of the additive and the plating time. The corrosion resistance of the plated surface was determined by gravimetric, potential measurement and corrosion current methods. The coating efficiencies were also determined. Variations in the plating parameters produced entirely new and different surface morphology. The quality of the electro-deposition of zinc was good as showed by the microstructural features of the plated surfaces. The electrodeposition process was sensitive to changes in additive concentration and plating time
