Abstract

Potentiodynamic polarization analysis was performed on heat-treated (quenched, normalized, or annealed) and epoxy-coated rebar steel samples in 3.5% NaCl solutions. Two types of epoxy coatings including a commercially available (Araldite LY 1556 with Aradur 2964 as curing agent, brushed) and FibreGlast with Resin 2000 epoxy coating (sprayed) using manufacturer’s recommendations were utilized in this study. Optical microscopy, hardness testing, and potentiodynamic polarization were carried out to study microstructure, hardness, and corrosion resistance of the bare and epoxy-coated rebar steel samples. Bare, as-received, rebar samples exhibited the highest corrosion rate of 11.93 μA/cm2 followed by quenched bare sample with 4.2 μA/cm2. Annealed and normalized rebar samples showed corrosion rates of 2.8 and 2.6 μA/cm2, respectively. All epoxy-coated samples exhibited lower corrosion rates compared to their uncoated counterparts.
