摘要

An orthogonal experimental group of saline soils with soluble salt anions (Cl-, SO42- and HCO3-) wasdesigned by orthogonal assistant and IBM SPSS statistics 21 software. The initial dynamicpotentiodynamic polarization of X80 steel embedded in different saline soils was tested using a threeelectrode system. The statistical range and variance in the measurement data, the corrosionmorphologies and composition of the X80 steel and the corrosion mechanism were analysed. Theresults show that the corrosion of X80 steel in S9 was the weakest, and the corrosion current densityreached 4.9E-7. The corrosive behaviour of X80 steel in different saline soils exhibited the followingorder: S9
