Title
(EN) SUPERABRASIVE MATERIALS AND METHODS OF MANUFACTURE
(FR) MATÉRIAUX SUPERABRASIFS ET PROCÉDÉS DE FABRICATION
Abstract
(EN)
Methods of manufacturing sintered superabrasive structures are disclosed. For example, a plurality of agglomerated granules comprising at least one superabrasive material may be provided and exposed to a pressure and a temperature sufficient to sinter the at least one superabrasive material. In another example, a plurality of agglomerated granules comprising diamond may be provided and exposed to a pressure and a temperature sufficient to form polycrystalline diamond. Articles of manufacture including at least one superabrasive material are disclosed. For example, a polycrystalline diamond compact may comprise a volume of polycrystalline diamond bonded to a substrate, wherein the volume of polycrystalline diamond includes a plurality of agglomerated granules which have been sintered. A drill bit comprising at least one cutting element including a volume of polycrystalline diamond bonded to a substrate wherein the volume of polycrystalline diamond includes a plurality of agglomerated granules which have been sintered is disclosed.

L'invention concerne des procédés de fabrication de structures superabrasives frittées. Par exemple, une pluralité de granules agglomérés comprenant au moins un matériau superabrasif peuvent être fournis et exposés à des pressions et températures suffisantes pour fritter le ou les matériaux superabrasifs. Dans un autre exemple, une pluralité de granules agglomérés comprenant du diamant peuvent être fournis et exposés à des pressions et températures suffisantes pour former un diamant polycristallin. L'invention concerne également des articles fabriqués incluant au moins un matériau superabrasif. Par exemple, une pastille de diamant polycristallin peut comprendre un volume de diamant polycristallin lié à un substrat, le volume de diamant polycristallin incluant une pluralité de granules agglomérés ayant été frittés. L'invention concerne également une mèche de foret comprenant au moins un élément de découpe incluant un volume de diamant polycristallin lié à un substrat, le volume de diamant polycristallin incluant une pluralité de granules agglomérés ayant été frittés.
