摘要

The rusts on the gauge face and non-gauge face of two rail steels (traditional C-Mn and novel Cu-Mo rail steel) were characterised after two years of service to corelate with an apparent visual observation of a lower corrosion rate in the case of the Cu-Mo rails. Rust samples were characterised by X-ray diffraction, Fourier transform infrared spectroscopy and Mössbauer spectroscopy. X-ray diffraction patterns showed diffuse peaks indicating poorly crystallised rust phases, while the phases identified by the other techniques were γ-FeOOH (lepidocrocite), α-FeOOH (goethite), Fe3-xO4 (magnetite), δ-FeOOH and α-Fe2O3 (haematite). The enhanced corrosion of the gauge face compared to non-gauge face for both rails and that of C-Mn rails compared to Cu-Mo rails was related to the higher amount of γ-FeOOH and lower amount of Fe3-xO4.
