An investigation of the plating quality effect of Allium cepa extract as addition agent on the electroplating of zinc on mild steel in acid chloride solution was done in the laboratory. Different extract concentrations, different plating time and fixed pH conditions were used to perform the experiments. A DC - supplier at defined operating parameters was used to perform the electroplating of zinc on mild steel. Scanning electron microscope (SEM) equipped with Energy Dispersive Spectroscopy (EDS) was used to examine the surface of the plated steel for surface morphology and surface elemental composition analysis. Variable surface characteristics were obtained depending upon the concentration of the additive and the plating time. Potential measurement, corrosion current and gravimetric methods were used to monitor and determine the corrosion resistance of the plated surface. The coating efficiencies were also determined. Entirely new and different metal substrate surface morphology were produced due to variations in the plating parameters used. The microstructural features of the plated surfaces showed that the quality of the electro-deposition of zinc was good.
