摘要：

Conversion films of vanadium oxides are potentiodynamically generated on vanadium in acetate electrolyte systems at high voltages. The microstructure of the about 5 mu m thin anodic films is investigated. X-ray diffraction and transmission electron microscopy indicate the films are complete amorphous. X-ray photoelectron spectroscopy (XPS) measurements show V 2p(3/2) binding energies of mixed valance vanadium sub oxides. Electron spin resonance (ESR) experiments on isolated films at 130 K point to paramagnetic V4+ centers in a. disordered octahedral oxygen surrounding. (C) 1999 Elsevier Science B.V.
