Abstract:The corrosion law of X80 steel in silty soils with different contents of sodium chloride and sodium sulfate is studied at different temperatures by using an orthogonal test group of three factors and three levels L9 (34) in conjunction with the results of electrochemical impedance spectroscopy, polarization curve, and microscopic images. The steel corrosion rate increases with the silty soil temperature. The presence of SO42− in silty soil inhibits corrosion in X80 steel. The corrosion mechanism involves compe… Show more
