Abstract
The corrosion regulation of Q235 steel in contaminated soils with different pH values between 3.5 and 4.5 was studied by means of polarization curves、scanning electron microscopy(SEM) and weight loss testing.Due to different cathodic depolarization mechanisms,the corrosion rate of Q235 steel was the lowest at the point of pH value 4.0.
