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