N2 - Several issues concerning the corrosion of clad rebar were examined. These include crevice corrosion resistance of 316L clad rebar, with and without corrosion penetration of stainless steel cladding to carbon steel, and corrosion associated with physical breeches in stainless steel cladding. Clad rebar was found to be very resistant to stable crevice corrosion and exhibited very low uniform corrosion rates, especially in comparison to carbon steel. Crevice corrosion of 316L clad rebar would be very unlikely except in severely chloride contaminated concrete. However, penetration of cladding by crevice attack leads to an Er value almost as low as carbon steel. Carbon steel exhibited a much greater uniform corrosion rate than stainless steel even in pH 12.6 electrolyte. Galvanic attack at pores, which exposed carbon steel, would be expected to accelerate corrosion of underlying steel. This was verified with electrochemical impedance measurements.
