Abstract

X-ray diffraction and electron backscattering diffraction analyses of the surfaces of α-Al₂O₃ coatings formed by aerosol deposition and heat treatment up to 1573 K reveal that the coatings have textures. A texture with the (0001) plane inclined approximately 15° away from the coating plane is observed in an as-deposited specimen. During heat treatment, the (0001) plane becomes almost parallel to the coating plane. Texture development is observed with increasing heat treatment temperature.
