Study on Initial Oxidation Film Formation Mechanism of T23 Steel at 600°C

Abstract:

Using scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS), the morphology observations and composition analtyses of a T23 steel oxidized in water vapor for 10~150min at 600°C were investigated, to study the initial formation mechanism. The result showed that the initial oxidation film was changed from acicular to flake shape. The second oxidation film layer appeared after oxidation for 40 min, and obvious double oxidation film structure was formed after 150 min with inner Cr-rich protective isometric crystal and outer Fe primarily columnar crystal.The oxide was Fe-rich phase in the whole oxidation process.
