摘要

The fretting corrosion behaviour of Ti-6Al-4V alloy in Ringer's solution was evaluated and compared with that of commercially pure titanium (CP-Ti). Free corrosion potential, morphology of the fretted zone, extent of formation and accumulation of debris and wear volume were used as parameters of evaluation. Both Ti-6Al-4V alloy and CP-Ti behave similarly in terms of change in free corrosion potential as a function of time, morphological features and wear mechanism. Ti-6Al-4V alloy, however, exhibits an increase in corrosion susceptibility, decrease in tendency for repassivation, higher amount of formation and accumulation of debris and an increase in wear volume compared with CP-Ti. The study points out the importance of material selection for implants that would encounter fretting corrosion.
