EIS study of nanoAlumina-polyester nanocomposite coatings and the effect of curing type on the corrosion properties

In this study, polyester coating and polyester-10%wt Al2O3 nanocomposite coating were applied on carbon steel substrate by electrostatic device and were cured in two different regime:microwave and oven. Morphology of nanoparticles was investigated by TEM and morphology of Coatings was evaluated by SEM. the effect of curing type and adding Alumina nanoparticles on corrosion properties was studied by EIS. Results indicate a significant increase in corrosionprotection performance of nanocomposite coatings than pure polyester coatings and better corrosion resistance for nanocomposite coatings cured in microwave
