Abstract
Mild Steel is a metal that is used in various industries because of its good mechanical properties, however there is a need to improve its physical and tribological properties, hence the reason for introducing coating. This process has proven over time to be an effective method for reducing the corrosion rate of mild steel. This study used zinc as a coating material for mild steel and also used green additives during the electrodeposition process to enhance the physical and mechanical properties of the zinc coating. The plating times used were 15 and 25 minutes. The electrical properties were examined with the aid of a voltage-ammeter device. The Digi-Ivy Potentiostat was used in studying the corrosion properties of the coatings. The microstructural study of the coated samples was carried out using the Scanning Electron Microscope (SEM). It was discovered that the physical, electrical conductivity, corrosion resistance properties and surface morphology of the coated samples improved when Cassia fistula and Citrus sinesis in certain concentrations were used. COMSOL Multiphysics software was used to validate the experimental data that showed that as plating time increases, the mass deposited on the cathode (mild steel) increased.
