摘要：
The initial oxidation of type 430 stainless steel was studied in O2H2O-N-2 atmospheres at 1273 K up to 180 s. The morphology of the oxide films changed with oxidation time. Isolated oxide particles grew in the initial 30 s, then the particles started to merge, but a compact film was not formed even after 120 s oxidation. The oxidation rate was high for 30 s and then decreased, but did not fit any oxidation rate law. Films were composed of only the corundum type (Fe,Cr)(2)O-3 oxide. The surface and bulk concentration of both Fe and Cr ions changed in the initial 30 s, and then reached steady values. The oxides were found to orient along the c-axis of the hexagonal cell after 30 s oxidation. Morphology, composition, structure and growth rates were not affected by the oxidizing atmosphere, but the preferred c-axis orientation was enhanced with high p(H2O).
