The role of UV illumination on the NaCl-induced atmospheric corrosion of Q235 carbon steel

In this work, the effect of ultraviolet (UV) illumination on the NaCl-induced atmospheric corrosion of Q235 carbon steel was investigated. UV illumination strongly affected the NaCl-induced atmospheric corrosion of Q235 carbon steel by the photovoltaic effect of the corrosion products that have semiconductor properties, which resulted in a significant increase in the NaCl-induced atmospheric corrosion rate and a positive photo-voltage.
