The microstructure of the films was characterized with SEM, TEM, and XRD. The chemical state of the titanium oxide of the films was analyzed using XPS. The results indicated that the vacuum-plasma sprayed nanostructured titanium oxide films possessed a corallike structure with small pores and agglomerated grains, which was composed of nanosized particles. The main phases of the films were anatase and rutile, and their relative content was determined by the plasma parameters. Low-valence titanium cations were also found in the films. 关键词: Plasma spraying;Vacuum technology;Titanium oxides;Nanostructured materials;Film preparation;Scanning electron microscopy;Transmission electron microscopy;X ray crystallography;X ray photoelectron spectroscopy;Crystal microstructure;Positive ions;Vacuum-plasma spraying
