| Abstract | The initial corrosion behaviors of carbon steel Q235 in the atmosphere with different concentrations Of SO2 were investigated by SEM/EDAX and FTIR. The corrosion kinetics results showed the variation of thickness loss of Q235 is related to concentrations Of SO2. When the concentration Of SO2 was relatively low, the thickness loss increased slowly, and when the concentration Of SO2 was relatively high, the thickness loss decreased rapidly. The concentration Of SO2 has a little effect on sulfate in the products, but facilitated the formations of oxide or hydrate in the rust layer. In all conditions, the corrosion products included FeSO4 center dot 7H(2)O, Fe-2(SO4)(3)center dot 9H(2)O, gamma-FeOOH and amorphous delta-FeOOH, but the concentration Of SO2 was enhanced to 0.5% (volume fraction), alpha-FeOOH was detected in the corrosion products. In the atmosphere with 0.05%SO2, rust nests appeared in the rust layer and the elements inside and outside the nest were great different, and a probable mechanism was proposed. |
