Anodic oxide films of the titanium alloy Ti-10V-2Fe-3Al in ammonium tartrate electrolyte without hydrofluoric acid or fluoride were fabricated. The morphology,components,and microstructure of the films were characterized by scanning electron mi-croscopy(SEM) ,X-ray photoelectron spectroscopy(XPS) ,X-ray diffraction(XRD) ,and Raman spectroscopy. The results showed that the films were thick,uniform,and nontransparent. Such films exhibited sedimentary morphology,with a thickness of about 3 μm,and the pore diameters of the deposits ranged from several hundred nanometers to 1.5 μm. The films were mainly titanium dioxide. Some coke-like deposits,which may contain or be changed by OH,NH,C-C,C-O,and C=O groups,were doped in the films. The films were mainly amorphous with a small amount of anatase and rutile phase.
Anodic oxide films of the titanium alloy Ti-10V-2Fe-3Al in ammonium tartrate electrolyte without hydrofluoric acid or fluoride were fabricated. The morphology, components, and microstructure of the films were characterized by scanning electron mi-croscopy (SEM) ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and Raman spectroscopy. The results showed that the films were thick, uniform, and nontransparent. Such films rendered sedimentary morphology, with a thickness of about 3 μm, and the pore diameters of the deposits ranged from several hundred nanometers to 1.5 μm. The films were mainly titanium dioxide. Some coke-like deposits, which may contain or be changed by OH, NH, CC, CO, and C═O groups, were doped in the films. The films were mainly amorphous with a small amount of anatase and rutile phase.
