영문 초록

  In order to study for corrosion behavior of reinforcing steel with oxidation layer, the characteristics of corrosion behavior were measured by polarization resistance method and cyclic potentiodynamic method.
  Experiments were done with various NaCl concentrations and with immersion time in simulated concrete pore solution(SPS).
  Rebars were coated by epoxy except corrosion area and except connecting area with potentiometer.
  The corrosion potential of rebar with oxidation layer was higher than that without oxidation layer and it also showed two anodic-nose.
  By the result of potentiodynamic method, the potential curve shifted to low potential region with time and anodic-nose was appeared with 3% NaCl solution after 15 days.
  By the result of cyclic Potentiodynamic method, the types of corrosion were different according to concentrations.
