摘要: The mobilities of various electrolyte-derived species in amorphous anodic titania have been determined, with stabilization the oxide structure by incorporation silicon from a suptter-deposited Ti-6 atom % Si alloy. From comparison distributions marker and films formed at high current efficiency, boron, chromium, molybdenum, tungsten migrate outward more slowly than do Ti 4+ ions. Their migration rates, relative to that ions, correlate well energies respective metal-oxygen bonds. Further, chromium incorporated into film chromate electrolyte are mainly present trivalent state indicating reduction Cr 6+ ions 3+ growing oxide. This can be explained considering influences on hand titania.
