| Abstract | To clarify some features of the atmospheric corrosion mechanism, the corrosion performance of Al bearing steels after wet/dry cyclic corrosion tests were studied by gravimetry, SEM, X-ray diffraction (XRD), potentiodynamic polarisation tests and electrochemical impedance spectra ( EIS). The results showed that rusted Al bearing steel presented a better corrosion resistance than that of rusted plain carbon steel (Q235) in 0 center dot 3% NaCl (i.e. simulating a marine environment) solution; moreover, the corrosion resistance of Al bearing steel increased with increasing Al content. The formation of a spinel double oxide containing Al( FeAl2O4) in Al alloying steels was observed, which refined the structure of the inner rust layer, suppressed the anodic dissolution and accelerated the cathodic reduction. In addition, Al alloying increased the content of gamma-FeOOH and decreased that of b-FeOOH. However, in NaHSO3 solution ( i.e. simulating an industrial environment), the rust layer on Al bearing steel did not possess a protective ability, and the rust layer formed was not physically or chemically stable. |
