Abstract
In this paper, epoxy coatings were modified by adding 5 wt.%, 10 wt.% or 20 wt.% of nano-sized titanium powder respectively. Correspondingly corrosion performance of the modified coatings was studied by electrochemical impedance spectroscopy (EIS) in 3.5% NaCl aqueous solution. The results showed that with high ionic resistance through the coating and low breakpoint frequency, the coating with 10 wt.% nano-sized titanium powder possessed the best corrosion resistance among the coatings tested, which might have resulted from the lowest diffusion coefficient for the inward migration of aggressive media through the coating in the given system.
