EFFECTS OF SRB ON CORROSION OF Q235 STEEL IN Cl- CONTAINING SOILS
在不同Cl-含量土壤中硫酸盐还原菌对Q235钢腐蚀的影响

The effects of Sulfate Reducing Bacterial (SRB) on corrosion of Q235 steel in soils containing Cl - have been studied.Bacterial analyses,weight loss,Electrochemical Impedance Spectroscopy,Scanning Electron Microscopy (SEM) and EDXA were used.The results shown that corrosion rate and pitting rate of Q235 steel in soils with different Cl - content and SRB are larger than those without SRB.Corrosion rate and pitting rate of Q235 steel increases with the increasing Cl - content of soils and which reaches a peak when the Cl - content of soils is about 0.5%,then decreass with funther increasing Cl - content in soils.
