Abstract (EN): Highly porous Ti was investigated under fretting-corrosion conditions as a function of load and amplitude. To obtain a correlation between mechanical and electrochemical responses according to amplitude, a new representative master curve was suggested: the A ratio (dissipated energy over total energy) vs. 1st OCP drop that fitted well the fretting-corrosion behaviour. Fretting-corrosion mechanisms were presented and a fretting map was illustrated. There was a significant load- and amplitude-dependent response, showing gross slip and partial slip regimes can occur with expected OCP variations. The promising structure of highly porous Ti was preserved after 16 h of fretting-corrosion under severe solicitations.
