Abstract Electrochemical impedance spectroscopy (EIS) was co upled with differential scanning calorimetry (DSC) and X-ray photoelectron spect roscopy (XPS) methods to investigate the effects of nano-Ti particle on the corr osion resistance of an epoxy coating on carbon steel.Four systems were studied:a clear coat and three pigmented coatings (with 0.1%,05%,1% nano-Ti).Impedance measurements showed that nano-Ti particle could improve the corrosion resistance of the coating;and the optimal addition is 0.5% (mass%).The results obtained by D SC and XPS showed that the nano-Ti particle enhanced interactions with epoxy res in.Addition the nano-Ti particles into epoxy resin can act two opposite effects: the beneficial effect is attributed to a chemical reaction between the nano-Ti powder and the epoxy resin,which improves the barrier effectiveness of the coati ng; this outweighs the harmful effect of an increase in the number of pores in t he coating.
