Abstract

La présente invention concerne un procédé de fabrication d’une pièce en composite de titane et de nano-diamants et la pièce ainsi obtenue, consistant à mélanger de la poudre de titane et de la poudre de nano-diamants, à précompacter le mélange et appliquer un traitement par frittage caractérisé en ce que : La proportion en masse de la poudre de nano-diamants est comprise entre 5 et 15% de la masse totale du mélange pulvérulentLe diamètre moyen des particules de nano-diamants est compris entre 4 et 100 nanomètresLe diamètre moyen des particules de titane est compris entre 10 et 45 micronsL’étape de frittage du mélange pulvérulent précompacté est réalisée dans un creuset placé entre deux électrodes en graphite reliées à une source électrique, sous atmosphère inerte ou sous vide, l'ensemble étant soumis à une pression comprise entre 20 et 400 mégapascals sous l'action d'une presse hydraulique, à une température comprise entre 800°C et 1300 °C.
