Laser cleaning has found successful applications in automotive, shipbuilding and artwork conservation, yet haven’t applied in the construction field. The laser beam have been expected to remove corrosion products and contaminations on the corroded surface completely. In this study, Polarization curves of laser-treated carbon steel plate were tested to reveal the effect of laser irradiation on electrochemical properties of carbon steel plate, and surface chemical composition was identified using X-ray diffraction (XRD). The correlation between corrosion resistance and laser treatment was established.
