摘要：
Fe2O3, Fe3O4 and Fe(OH)(3) as three different corrosion products of iron and their mixture were investigated in the 0.2 similar to 2.0 THz using terahertz time-domain spectroscopy (THz-TDS) in vacuum environment at room temperature. Frequency and reflectivity of Fe2O3, Fe3O4, Fe(OH)(3) and their mixture were calculated by fourier transform. There are no peaks in the THz range, but the reflectivities of samples have significant differences. The results demonstrate that the three different corrosion products of iron and their mixture can be analyzed distinctly according to the characteristics in THz range. THz-TDS can be used in further analysis of iron corrosion and pipeline corrosion detection.
