More Information
Summary:The present disclosure relates to cutting tools incorporating polycrystalline diamond bodies used for subterranean drilling applications, and more particularly, to a thermally stable polycrystalline diamond body joined to a substrate to form a cutting element. The thermally stable polycrystalline diamond body may be binderless polycrystalline diamond or a non-metal catalyst polycrystalline diamond. A polycrystalline cubic boron nitride layer is also provided, bonded on one side to the polycrystalline diamond body and on the other side to the substrate. La présente invention concerne des outils de coupe incorporant des corps de diamant polycristallin utilisés pour des applications de forage souterrain, et plus particulièrement, un corps de diamant polycristallin stable thermiquement joint à un substrat pour former un élément de coupe. Le corps de diamant polycristallin stable thermiquement peut être un diamant polycristallin exempt de liant ou un diamant polycristallin à catalyseur non métallique. Une couche de nitrure de bore cubique polycristallin est également disposée, liée sur un côté du corps de diamant polycristallin et sur l'autre côté au substrat.
