Title (EN) COMBINED FIELD ASSISTED SINTERING TECHNIQUES AND HTHP SINTERING TECHNIQUES FOR FORMING POLYCRYSTALLINE DIAMOND COMPACTS AND EARTH-BORING TOOLS, AND SINTERING SYSTEMS FOR PERFORMING SUCH METHODS
(FR) TECHNIQUES DE FRITTAGE ASSISTÉES PAR CHAMP COMBINÉ ET TECHNIQUES DE FRITTAGE HTHP POUR FORMER DES DIAMANTS POLYCRISTALLINS ET OUTILS DE FORAGE, ET SYSTÈMES DE FRITTAGE UTILISÉS POUR CES PROCÉDÉS
Abstract: front page image
(EN)Methods of forming noncrystalline diamond compacts include employing field assisted sintering techniques with high temperature and high pressure sintering techniques. For example, a particle mixture that includes diamond particles may be sintered by subjecting the particle mixture to a high temperature and high pressure sintering cycle, and pulsing direct electrical current through the particle mixture during at least a portion of the high temperature and high pressure sintering cycle. The polycrystal!ine diamond compacts may be used to form cutting elements for earth-boring tools. Sintering systems are configured to perform such sintering processes.
(FR)Cette invention concerne des procédés permettant de former des diamants polycristallins en utilisant des techniques de frittage assistées et des techniques de frittage à haute température et à haute pression. Par exemple, un mélange de particules contenant des particules de diamant peut être fritté en soumettant ledit mélange à un cycle de frittage à haute température et haute pression, et en envoyant du courant continu dans ledit mélange pendant au moins une partie du cycle. Les diamants polycristallins peuvent être utilisés pour former des éléments de coupe d'outils de forage. L'invention concerne également des systèmes de frittage conçus pour exécuter ces procédés.
