- Abstract
The effects of simulated acid rain (SAR) on corrosion behaviours of Q235 steel in acidic soil were studied using potentiodynamic polarisation, electrochemical impedance spectroscopy measurements, scanning electron microscopy and X-ray diffraction. The results indicated that the SAR heavily increased the corrosion rate of the steel in the acidic soil. The corrosion rate of the steel increased with decreasing SAR pH values. The corrosive characteristics of the soil obviously increased because of leaching of the acid rain. The corrosion products of Q235 steel surface were mainly composed of Fe2O3, Fe3O4 and some soil components such as SiO2.
