抄録
The present authors made observations on oxide films formed on the surface layers of Fe-Cr-Al alloys and electrical heating alloys (Kanthal A and Fe-Cr JIS No. 2), when the alloys came into contact with air at high temperature (700∼1000°C), by using the transmission electron diffraction method. Thereby the authors detected heat-resisting films consisting of fine γ- and α-Al2O3 crystals which are supposed to be already in existence on the surfaces of excellent heat-resisting Fe-Cr-Al alloys (ca. 2∼5%Al) and electrical heating alloys in the earliest stage of oxidation. In the course of the observations, the authors studied the effects that the quantities of Al and Cr contained in the alloys and their oxidation temperatures exert on the high temperature oxidation films. The present studies also verified experimentally that Cr2O3 and α-Fe2O3 crystals produced on the surfaces of electrical heating alloys at 700° for 3 min change into α-Al2O3 crystals in the course of alumino-thermic reaction at 1000°C.
