摘要：
Corrosion behavior of steel Q235 was investigated during natural evaporation in soils with and without sulfate reducing bacteria (SRB) by microbiological analysis, electrochemical impedance spectroscopy (EIS), energy dispersive X-ray analysis (EDXA) and electron-probe X-ray microanalysis (EPMA). The results show that during natural evaporation, oxygen content increases, amounts of SRB decrease, and the corrosion rates of steel Q235 increase with decreasing humidity of soils with and without SRB. Increments of the corrosion rates are much bigger in soils with SRB than those without SRB.
