Abstract
Abstract This paper focuses on study of the kinetics and the mechanism of passive film formation on novel superelastic biomedical Ti–22Nb–6Ta (at.%) alloy in simulated physiological solutions using AES, XPS and electrochemical techniques in comparison with commercially pure titanium and Nitinol. Ti–22Nb–6Ta alloy manifests a strong trend to protective passive film formation during first stage of oxidation in simulated physiological solutions. It is shown that Ti–Nb–Ta electrochemical characteristics are comparable to those of titanium and Nitinol and the alloy can be recommended for use in implantology.
