Abstract (EN): Micro-arc oxidation is being applied to overcome the poor wear resistance of Ti that also enables to give bio-functions with the incorporation of bioactive agents such as Ca, P and Sr. In the present work, micro arc oxidation was used to obtain Ca-P-Sr-doped hard TiO2 porous layers with three different amounts of Sr and tribocorrosion behaviour was investigated. Results showed that the distribution of anatase and rutile in the porous oxide layer led to a less visible damage and lower COF values, where the group containing more Sr presented the best tribocorrosion response mainly due to the increased amount of rutile.
