For evaluating the corrosive performance of the soil in Wuhan, the composition of typical soil in Wuhan, Hubei Province was sampled and analyzed.The corrosion behavior of Q235 steel in Wuhan soil was studied by using actual soil buried test and accelerated corrosion test with controlling temperature and humidity and applying super depth of field microscope, focused ion beam scanning electron microscope(FIB-SEM)and electrochemical workstation.Experimental results showed that the soil environment in Wuhan was of “light” corrosion grade, and the Q235 steel had changed from non-uniform corrosion to general corrosion, and its surface showed pitting corrosion and spalling.In addition, the degree of corrosion increased with the extension of time, and its corrosion rate decreased and stabilized with the extension of time.With the progress of corrosion, the self-corrosion potential of Q235 steel increased, and the self-corrosion current density decreased.In summary, Q235 steel had acceptable corrosion resistance in Wuhan soil environment, which was suitable for large-scale use as structural materials.
