Ce travail porte sur l\u2019\u00e9tude du comportement tribologique sans lubrification et \u00e9lectrochimique dans la salive artificielle des alliages TiNi (50\/50) et TA6V4 pour les applications en orthodontie (implants dentaires). L’alliage TiNi (50\/50) a \u00e9t\u00e9 pr\u00e9par\u00e9 dans un four \u00e0 induction sous vide alors que l’alliage commercial TA6V4 sera utilis\u00e9 comme mat\u00e9riau de r\u00e9f\u00e9rence. L\u2019analyse microstructurale et la composition chimique des deux\u00a0 alliages TiNi et TA6V4 a \u00e9t\u00e9 r\u00e9alis\u00e9e par microscopie \u00e9lectronique \u00e0 balayage (MEB) coupl\u00e9e \u00e0 l\u2019EDS. Les r\u00e9sultats montrent que l’alliage TiNi pr\u00e9sente une meilleure r\u00e9sistance \u00e0 l’usure par glissement \u00e0 sec (1,327×10-4<\/sup> mm3<\/sup>\/Nm) par comparaison avec l’alliage TA6V4 (9,506×10-4<\/sup> mm3<\/sup>\/Nm). Les m\u00e9canismes d\u2019usure ont \u00e9t\u00e9 clairement identifi\u00e9s pour les deux alliages et sont principalement bas\u00e9s sur une usure abrasive et adh\u00e9sive pour l’alliage TiNi, et une usure abrasive associ\u00e9e \u00e0 une oxydation, pour l\u2019alliage TA6V4. L’\u00e9tude \u00e9lectrochimique a r\u00e9v\u00e9l\u00e9 que les deux alliages pr\u00e9sentent un caract\u00e8re passif avec une r\u00e9sistance \u00e9lev\u00e9e \u00e0 la corrosion.<\/p>\n
