Abstract
The corrosion behaviour of Ti–25Mo alloy in
0.9 wt% NaCl was evaluated by potentiodynamic polarization,
electrochemical impedance spectroscopy (EIS) and
compared with that of commercially pure titanium (CP-Ti).
The corrosion behaviour of Ti–25Mo alloy has been
reported for the first time in this paper. The microstructure
and structural characteristics were also examined using
optical microscopy and X-ray diffraction (XRD), respectively. The study reveals that Ti–25Mo alloy possesses a b-phase microstructure. The Ti–25Mo alloy exhibits higher passivation range, lower average passive current density (ipass) and higher charge transfer resistance (Rct) compared
to that of CP-Ti. Based on the corrosion protection ability,
Ti–25Mo alloy can be a suitable alternative material for
orthopaedic implant applications.
