“…The clear change in slope at 10 V is due to the influence of a change in the dielectric constant of the film as crystallization leads to an increase in ε (ε amorphous ¾ D 4-40, ε anatase ¾ D 48). 7,8 Also supporting the slower crystallization in phosphoric acid is the capacitance behavior C P of the porous layer part Fig. 3.…”

For a better understanding of the oxide growth and final film properties upon anodization of titanium in sulfuric and phosphoric acid containing electrolytes, the electrochemical behavior as studied by a.c. impedance was correlated to microstructural analysis (TEM, Raman). Chemical depth profiling of the films was performed with glow discharge optical emission spectroscopy (GDOES), XPS and RBS. The fitted capacitances and resistances from a.c. impedance measurements were greatly influenced by the ongoing crystallization as well as by film porosity as a function of increasing anodization potential. GDOES revealed a small sulfur contamination (with its maximum before the oxide-metal interface) upon anodization in 1 M H 2 SO 4 and a significant phosphorus content throughout the oxides for films grown in 1 M H 3 PO 4 , showing an accumulation at the surface. Small impurities of carbon in all films as well as an accumulation of hydrogen at/after the interface oxide-metal were also observed. Quantification of the hydrogen content by elastic recoil detection analysis (ERDA) indicated a peak concentration of 20-30 at%.

Abstract:The electrochemical anodic oxidation method was used to prepare thin films of titanium dioxide (TiO 2 ) semiconductors (undoped and doped with Mn). These films were used to test the oxidation of methanol (CH 3 OH), the degree of which was quantified by measuring the current density produced as a function of an applied potential between 0.5 V and 5.0 V. The value of the potential to be applied in order to prevent fast electron-hole recombination was determined. The observed phenomenon is explained by considering the wave nature of the electron.

“…It was demonstrated that titanium and its alloys with their stable titanium dioxide films (in two allotropic forms: rutile and anatase) are most effective for apatite nucleation [18 -20]. Anodic oxidation is a superior method to obtain rough, porous oxide surfaces [21,22] proper to develop the apatite-forming ability.…”

The properties of the anodic oxide films formed on titanium and its implant alloys Ti-5Al-4V and Ti-6Al-4Fe are investigated in this paper. Anodic oxide films were prepared by electrochemical treatment in 3M sulphuric acid solution at 60 V for 1 min, followed by a thermal treatment consisting of heating at 500 8C for 24 h and then cooling in water. Electrochemical impedance spectroscopy (EIS) measurements were carried out at open circuit potential. Nyquist and Bode spectra exhibit a two-time constant system, attesting an oxide with two layers: a barrier inner oxide and a porous outer one. All spectra change in time, indicating a thickening of the films. Open circuit potentials were monitored (long-term, 25,000 exposure hours) in Ringer 2 solution of different pH values (6.98, 4.35, 2.5) for titanium, Ti5Al-4V and Ti-6Al-4Fe alloy but without treatment with the purpose to compare the biomaterial behaviour. It was pointed out some variations of the open circuit potentials around electropositive values, suggesting slow dissolution, re-passivation or adsorption processes.
