The chemical composition and structure of these coatings were determined by X-ray photoelectron spectroscopy (XPS), glancing angle X-ray diffraction (XRD) and scanning electron microscopy (SEM). As-prepared oxide coatings were dense, adherent and essentially non-stoichiometric. X-ray diffraction analysis indicated that the oxide coatings may consist of ultrafine crystallites. These coatings exhibited considerable plastic deformation at room temperature. 关键词: MORPHOLOGY; ATOMIC FORCE MICROSCOPY; FILMS; NANOCRYSTALLINE; TEMPERATURE; OXIDE
