dc.description.abstract Titanium and its alloys are widely used as dental implants due to their low density, excellent biocompatibility, mechanical properties and corrosion resistance. However, during their life time Ti6Al4V biomedical alloys are subjected to different mechanical actions (i.e.,sliding or fretting), thus resulting in a tribocorrosion system, which is an irreversible materia ldegradation process due to the combine deffect of corrosion and wear. In this study, the tribo-electrochemical behavior of cast and sintered (by powder metallurgy) Ti6Al4V alloy in artificial human saliva solution with out and with fluoride additions of 100 ppm and 1000 ppm and in an average industrial mouth wash solution with a 112 ppm fluoride content have been investigated by different electrochemical techniques. The same tribocorrosion mechanisms were found in the cast and sintered titanium alloys, although slightly different wear debris behavior was observed. At low applied passive potentials, wear rates are similar to those obtained under equilibrium conditions (Open Circuit Potential). There exists a critical fluoride concentration above which corrosion and tribocorrosion rates increase. es_ES
