Résumé
The aim of the present work was to study corrosion and electrochemical behavior of Ti-22Nb-6Ta (at. %) superelastic alloy in comparison with commercially pure titanium (cp-Ti) under simulated service conditions of load-bearing bone implants, i.e. under cyclic load in simulated body fluid environment. Open circuit potential (OCP) measurements were carried out on wire samples in Hank’s solution at 37°C applying bending load (maximum induced strain 0.8 %) up to 75×103 cycles or sample failure. It is shown that Ti-22Nb-6Ta alloy is superior to cp-Ti in terms of corrosion fatigue behavior. In particular, it possesses higher OCP values and its passive oxide film is more resistant to the impact of cyclic loading; fatigue life of the alloy is longer.
