NaOH and HNO,. After film growth, AC impedance measurements were performed in the frequency range 0.1 Hz-1OOKHz. The impedance spectra of the oxides showed a multilayer structure as the oxide thickness increased, due to anion incorporation from the electrolyte and the corrosion process enhanced by
Impedance measurements and photocurrent spectroscopy have been used to examine the dependence on growth rate of the solid state properties of thin ( -c 20 nm) anodic oxide films on titanium. At room temperature, the relative permittivity and defect concentration profiles in the oxide were found to d
The effects of formation conditions, especially the electrolyte, on the non-stoichiometry of the anodic oxide films of titanium have been studied. The electrolytes were molten sodium nitrite, molten sodium nitrate and molten mixture of these salts and sodium peroxide, which was used to change the ox
