摘要：
This study had dealt with the resistance to corrosion with nanostructured materials since they consume less energy and was employed in a variety of lightweight applications. For this study, nano-sized cerium oxide had been used as an anti-corrosive inhibition. This CeO2 nanoparticle was synthesized utilizing a hydrothermal technique. The coating was obtained by mixing various concentrations of CeO2 nanoparticles with a water-based epoxy resin. Resistance to corrosion with the formulated coating on a mild steel substrate was tested inside a simulated concrete pore solution containing 0.5 M NaCl solution. The corrosion inhibiting effect was evaluated by immersing the nano CeO2 - Epoxy composite coated mild steel substrate in a simulated concrete pore solution utilizing electrochemical impedance spectroscopy methodology. Tafel tests were used to calculate the corrosion rate. The outcomes showed that the nano-sized cerium oxide as filler material for epoxy covering displayed a superior corrosion inhibiting effect along with the commencement of a stable protective shield when compared to substrate of pure epoxy and without coating.
