%X A laboratory study of the atmospheric corrosion of carbon steel deposited with (NH4)2SO4 in the presence of SO2 isreported. The different levels of (NH4)2SO4 (0, 15, 30, 45, 60μg.cm-2) were added on the surface of the samplesbefore the exposure. The corrosion was investigated by a combination of gravimetry, Fourier transform infraredspectroscope and scanning electron microscopy. A detailed knowledge about the corrosion products was acquired,both quantitatively and qualitatively. The results show that the metal loss increased and the increasing tendency ofcorrosion rates slowed down with the increasing exposure time. The phase constituents of the corrosion products aremainly c-FeO(OH), γ-FeO(OH), and δ-FeO(OH).
