Abstract

Characterization of oxide films formed on brightly annealed Al–added 18%Cr steel was performed by glow discharge optical emission spectrometry, transmission electron microscopy, and hard X–ray photoelectron spectroscopy. The experimental data indicated that the oxide films with an average thickness of about 15 nm were mainly composed of amorphous Al2O3, which was identified from the locations of the first and second rings in the halo pattern obtained by electron diffraction. The data also suggested the presence of Si4+ and Si3+ in the outermost surface layer of the oxide films. The formation of amorphous Al2O3 found in the brightly annealed Al–added 18%Cr steel is discussed on the basis of the present experimental data, with reference to the molecular–dynamics calculation made by Gutierrez and Johansson [Phys. Rev. B. 65 (2002) 104202].
