Corrosion Resistance and Mechanism of Steel Rebar Coated with Three Types of Enamel
Corrosion resistances of steel rebar with different enamel coatings, and with fusion bonded epoxy coatings were investigated in 3.5. wt.% NaCl solution by Electrochemical Impedance Spectroscopy (EIS). The sensitivity to damage of the coatings was characterized and it was found that the pure and double enamel coatings can protect the steel rebar better than the mixed enamel coating due to their denser microstructures with isolated pores. Damaged enamel coating was locally corroded, whereas corrosion at a defect often undercut the epoxy coating. The intact epoxy coating offered better corrosion protection than the enamel coatings. © 2012 Elsevier Ltd.
