AbstractThe characterizations of the corrosion products formed during long term atmosphere exposure at Beijing area containing minor H2S, SO2, NO2 and damp air have been studied by FTIR and XRD. Goethite, lepidocrocite and delta-FeOOH existed in the corrosion products, which formed on all of the samples independent of the different conditions and different steels. It shows that the corrosion products of carbon steels exposed for one year are similar to those exposed for two years; the phase constituents of the inner corrosion product at the upper surface are the same as those at the downward surface, but the outer product phases are different; the corrosion products of the same substrate pre-corroded by different pollutants are the same. It is concluded that the pre-corrosion means have no obvious effect to the corrosion phases of carbon steels after exposed over one year and the reasons are discussed here.
