Title (EN) CUTTING ELEMENTS AND METHODS FOR FABRICATING DIAMOND COMPACTS AND CUTTING ELEMENTS WITH FUNCTIONALIZED NANOPARTICLES
(FR) ÉLÉMENTS DE COUPE ET PROCÉDÉS DE FABRICATION DE COMPRIMÉS DE DIAMANT ET D'ÉLÉMENTS DE COUPE COMPRENANT DES NANOPARTICULES FONCTIONNALISÉES
Abstract:
(EN) A polycrystalline diamond compact (PDC) cutting element includes a substrate and a polycrystalline diamond compact. The substrate comprises a ceramic-metal composite material including hard ceramic particles in a metal matrix. The poly crystalline diamond compact includes interbonded diamond particles. Interstitial material disposed within interstitial spaces between the interbonded diamond particles comprises aluminum and at least one element of the ceramic-metal composite material of the substrate. A method of manufacturing such a PDC cutting element includes forming a mixture including diamond particles and particles of aluminum, and subjecting the mixture and a substrate to a high pressure, high temperature (HPHT) sintering process.
(FR) L'invention concerne un élément de coupe compact en diamant polycristallin (PDC) comprenant un substrat et un comprimé de diamant polycristallin. Le substrat comprend un matériau composite céramique-métal comprenant des particules de céramique dure dans une matrice métallique. Le compact en diamant polycristallin comprend des particules de diamant liées entre elles. Un matériau interstitiel disposé dans des espaces interstitiels entre les particules de diamant liées entre elles comprend de l'aluminium et au moins un élément du matériau composite céramique-métal du substrat. Un procédé de fabrication d'un tel élément de coupe PDC consiste à former un mélange comprenant des particules de diamant et des particules d'aluminium, et à soumettre le mélange et un substrat à un procédé de frittage à haute pression et haute température (HPHT).
