ABSTRACT
Zn-Mg-ZnO nanocomposite electrodeposits have better corrosion resistance to sodium chloride in the atmospheric environment and better than that of other zinc alloys of equal thickness and therefore, provide a better alternative for corrosion protection. Nano zinc coatings are deposited on mild steel by electro deposition. Besides corrosion protection and decoration, nanocoatings sometimes impart to the surface, specific mechanical and physical properties such as wear resistance, hardness, electrical properties, oxidation - resistance and thermal-insulating properties. The effect of addition of ZnO nanoparticles on the morphology of crystal size on zinc deposited surface and corrosion properties are investigated. The results showed that addition of nano additives in the deposition process of zinc significantly increased the corrosion resistance. The surface morphology of the zinc deposits was studied by scanning electron microscopy (SEM).
