The influences of water content on corrosion behavior of grounding steel in semi-desertification soil were studied by polarization curve technique and weightlessness method. The tested specimen surface was characterized by scanning electron microscopy(SEM),energy dispersive spectrometer(EDS),and X-ray diffraction(XRD). The experiment results show that moisture has a great influence on corrosion of steel,the corrosion rate of 20 steel increased to a maximum at a value and then decreased. To anslysis the formation mechanism of soil corrosion products.
