“…Marino et al 6 investigated the average anodization rate of Ti in buffered aqueous H 3 PO 4 solution under different pH, and the excellent stability of titanium in different pH phosphoric media was proved. Pure titanium (CP Ti) and titanium alloys (Ti64 and Ti10-2-3) were exposed to pressurized water at 300 °C by Selva et al 7 to explore their corrosion behavior. It was discovered that all titanium and titanium alloys exhibited the uniform corrosion due to simultaneous dissolution and continuous growth of oxide film.…”

The passivation behavior of Ti-6Al-4V alloy was studied by electrochemical and surface analyses, and a model was proposed to elucidate the connection between polarization time and properties of the passive film. Three stages of passive film growth can be divided based on the changes of current density during the formation process of passive film and the passive film grew and stabilized after polarized for 0~2000 s under 1.0 V vs. Ag/AgCl in 0.5 M H2SO4 solution. The chemical state of Ti at the topmost surface of passive film was independent of the polarization time, while the formation of oxides inside the passive film was promoted. The structure evolution of passive film was investigated by high-resolution XAS through the synchrotron radiation source. The formation and increase of thermodynamically stable rutile-TiO2 contributed to the enhancement of the impedance and corrosion resistance of passive film.
