Abstract
Properties of surface oxide layers formed on extended Kh18N10T steel specimens upon oxidation at residual pressure P = 10−4–101 mmHg under typical heating in a furnace and alternating-current (50 Hz) electrocontact heating (300°C) are studied. A strong activating effect of alternating-current heating on the oxidation of steel at P = 0.01 mmHg is noticed. Compared to typical heating in a furnace, electrocontact heating promotes saturation of the surface oxide with chromium and homogenization of the chromium distribution in the depth of the oxide and the resulting formation of iron chromite.
