Sažetak
Chemical and structural properties of the rust formed by corrosion of steel in water and (NH4)2SO4 solutions at 20 °C for time periods up to 6 months were investigated by X-ray diffraction, Fourier transform IR spectroscopy and 57Fe Mössbauer spectroscopy. Three oxide phases, y-FeOOH (lepidocrocite), Fe304 (magnetite) and a-FeOOH (goethite) were detected in the rust samples. The distribution of these phases in the rust was dependent on the time of corrosion and the concentration of (NH4)2SO4. 57Fe Mössbauer spectroscopy indicated the substoichiometric character of magnetite (Fe3_I04). Magnetite was not observed in the rust generated in 2M (NH4)2SO4 solution. Fourier transfrom IR spectroscopy was particularly useful in the detection of very small amounts of goethite and lepidocrocite in the rust. The strong influence of (NH4)2SO4 electrolyte on the corrosion of steel in aqueous medium was explained as a cumulative effect of two aggresive ions, NH4+ and SO42-.
