Abstractbiocompatibility. Vanadium-free Ti-6Al-7Nb alloy has been developed as a
potential alloy for providing improved corrosion and wear resistance for orthopedic
implant devices, and to avoid the toxicity of vanadium ion.
This work deals with the dependence of corrosion parameter of Ti-6Al-7Nb
alloy on compositional variation in the phases resulting from various heat treatments.
Electrochemical examinations were applied made in blood plasma solution involving
potential –time and dynamic polarizations for Ti-6Al-7Nb alloy of various heat
The corrosion parameters obtained from open circuit potential, and
potentiodynamic polarization for the alloy Ti-6Al-7Nb were superior for specimen
developed by solution treatment at 950oC and air cooled followed by aging in
comparison with that of other treatments.
