Abstract

The oxide films formed on SUS430 stainless steel under various conditions have been investigated by using infrared reflection absorption spectroscopy. A comparison of the spectra of the samples oxidized in moist atmosphere with those oxidized in dry atmosphere shows the important role of water vapor at 873 and 973 K. The abnormally rapid oxidation at 873 K in moist atmosphere with low oxygen pressure is characterized by rapid increasing of the intensity of the absorption band at about 550 cm−1. The frequency of this band shifts to a lower wave number as its intensity increases.
