Interaction of Ti–6 wt.% Si alloy with tissue fluid: experimental modeling

The methods of potentiodynamic polarization curves and quantitative Auger electron spectroscopy are used to determine the mechanism whereby a dense protective nanofilm (up to 20 nm thick) forms. The film consists of Ti 2 O, TiO, and Ti 2 O 3 lower titanium oxides and forms under the layer of TiO 2 (...

Description
Summary:The methods of potentiodynamic polarization curves and quantitative Auger electron spectroscopy are used to determine the mechanism whereby a dense protective nanofilm (up to 20 nm thick) forms. The film consists of Ti 2 O, TiO, and Ti 2 O 3 lower titanium oxides and forms under the layer of TiO 2 (10 nm) and oxygen chemisorbed over an orthopedic prosthesis (90.2 at.% Ti–9.8 at.% Si alloy) during electrolysis in a 3% NaCl solution, as the main component of the tissue fluid (Hank’s physiological solution).
