Title (EN) POLYCRYSTALLINE DIAMOND COMPACTS, METHODS OF FORMING POLYCRYSTALLINE DIAMOND, AND EARTH-BORING TOOLS
(FR) COMPRIMÉS DE DIAMANT POLYCRISTALLIN, PROCÉDÉS DE FORMATION DE DIAMANT POLYCRISTALLIN ET OUTILS DE FORAGE
Abstract:
(EN) A polycrystalline diamond compact includes a polycrystalline diamond material having a plurality of grains of diamond bonded to one another by inter-granular bonds and an intermetallic gamma prime (γ') or κ-carbide phase disposed within interstitial spaces between the inter-bonded diamond grains. The ordered intermetallic gamma prime (γ') or ҡ-carbide phase includes a Group VIII metal, aluminum, and a stabilizer. An earth-boring tool includes a bit body and a polycrystalline diamond compact secured to the bit body. A method of forming polycrystalline diamond includes subjecting diamond particles in the presence of a metal material comprising a Group VIII metal and aluminum to a pressure of at least 4.5 GPa and a temperature of at least 1,000°C to form inter-granular bonds between adjacent diamond particles, cooling the diamond particles and the metal material to a temperature below 500°C, and forming an intermetallic gamma prime (γ') or ҡ-carbide phase adjacent the diamond particles.
(FR) L'invention concerne un comprimé de diamant polycristallin, comprenant un matériau à base de diamant polycristallin ayant une pluralité de grains de diamant liés les uns aux autres par des liaisons intergranulaires et une phase intermétallique de carbure κ ou gamma prime (γ') disposée dans les espaces interstitiels entre les grains de diamant liés entre eux. La phase intermétallique ordonnée de carbure ҡ ou gamma prime (γ') comprend un métal du groupe VIII, de l'aluminium et un stabilisant. L'invention concerne également un outil de forage, comprenant un corps de trépan et un comprimé de diamant polycristallin bien fixé au corps de trépan. L'invention concerne également un procédé de formation de diamant polycristallin consistant à soumettre des particules de diamant, en présence d'un matériau métallique comprenant un métal du groupe VIII et de l'aluminium, à une pression d'au moins 4,5 GPa et une température d'au moins 1 000 °C pour former des liaisons intergranulaires entre des particules de diamant adjacentes, refroidir les particules de diamant et le matériau métallique à une température au-dessous de 500 °C et former une phase intermétallique de carbure ҡ ou gamma prime (γ') adjacente aux particules de diamant.
