Abstract

La présente invention concerne un diamant polycristallin modifié en surface et une méthode de traitement connexe. Le diamant polycristallin comprend un corps de diamant polycristallin, et des trous sont formés dans le corps du diamant polycristallin après le retrait dun métal catalyseur, lesdits trous étant intégrés à un métal non-catalyseur. Selon le diamant polycristallin modifié en surface et la méthode de traitement connexe de la présente invention, le métal catalyseur est retiré du corps du diamant polycristallin et le métal non-catalyseur est intégré aux trous qui sont formés à la surface du diamant polycristallin après le retrait du métal catalyseur. Ainsi, les dommages thermiques et liés au stress causés au diamant polycristallin pendant les opérations effectuées à température élevée sont éliminés. De plus, la méthode améliore la conductivité thermique de la surface du diamant polycristallin et réduit la température de la zone entourant le point de fonctionnement du diamant polycristallin, prolongeant ainsi la durée de vie du diamant polycristallin.
