Patent

CA 2760984

The present disclosure relates to cutting elements incorporating polycrystalline diamond bodies used for subterranean drilling applications, and more particularly, to polycrystalline diamond bodies having a high diamond content which are configured to provide improved properties of thermal stability and wear resistance, while maintaining a desired degree of impact resistance, when compared to prior polycrystalline diamond bodies, hi various embodiments disclosed herein, a cutting element with high diamond content includes a modified PCD structure and/or a modified interface (between the PCD body and a substrate), to provide superior performance.

La présente invention se rapporte à des éléments de coupe incorporant des corps en diamant polycristallin utilisés pour des applications de forage souterrain et, plus particulièrement, à des corps en diamant polycristallin ayant une teneur en diamant élevée et configurés pour donner de meilleures propriétés de stabilité thermique et de résistance à l'usure tout en maintenant un degré souhaité de résistance aux chocs lorsqu'ils sont comparés aux précédents corps en diamant polycristallin. Selon divers modes de réalisation, un élément de coupe ayant une teneur en diamant élevée comprend une structure PCD modifiée et/ou une interface modifiée (entre le corps en PCD et un substrat) pour offrir des performances supérieures.
