摘要

The performance effects of thiourea and dextrin as addition agents on the electroplating of zinc on mildsteel in acid chloride solution were experimentally investigated. The experiments were performedunder different additive concentrations, different plating time and fixed pH conditions. The zincelectroplating on mild steel was performed using a DC supply at defined operating parameters. Thesurface of the plated steel was examined using scanning electron microscopy (SEM) for surfacemorphology; and Energy Dispersive Spectroscopy (EDS) for surface elemental composition analysis.Different surface characteristics were obtained depending upon the concentration of the additive andthe plating time. The corrosion resistance of the plated surface was determined by gravimetric method.The quality of the electro-deposition of zinc was good as indicated by the microstructural feature of theplated surface. The electrodeposition process was sensitive to changes in additive concentration andplating time. Variations in the plating parameters produced entirely new and different surfacemorphology.
