Abstract

In this study, ZnO-Cr2O3/epoxy nanocomposites are employed to protect Mild steel Corrosion in 3. 5% NaCl solution. The Corrosion performances of the nanocomposites coatings were evaluated by using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements. Electrochemical measurements show that ZnO-Cr2O3 nanocomposite coated has good inhibitive properties with PE% of ~99% at 0. 04 gr/L concentration on Mild steel Corrosion in 3. 5% NaCl solution. The results indicated that the incorporation of ZnO-Cr2O3 nanoparticle into epoxy resin coating significantly decrease the Corrosion current as well as the hardness of Epoxy coatings. ZnO-Cr2O3 nanoparticles are able to cure the defect in epoxy resin and prevent the diffusion of corrosive electrolyte to Mild steel substrate.
