Abstract:
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. In 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.

Claim (Index 19):
A cutting element comprising:\n a substrate comprising a substrate interface surface, the substrate interface surface comprising a protrusion; and a polycrystalline diamond body formed by sintering at a cold cell pressure greater than 5.4 GPa, the polycrystalline diamond body comprising,\n a diamond interface surface interfacing with the substrate interface surface, \n a top surface opposite the diamond interface surface; \n a cutting edge meeting the top surface; and \n a material microstructure comprising a plurality of bonded-together diamond grains having an average grain size and interstitial regions between the diamond grains, the material microstructure comprising a first layer proximate the cutting edge and a second layer proximate the interface surface, \n wherein at least a region of the first layer has a diamond volume fraction, as measured by electron backscatter diffraction, greater than (0.9077)\u00b7(the diamond average grain size\u03020.0221), with the diamond average grain size provided in microns, wherein at least a region of the first layer includes a plurality of the interstitial regions that are substantially free of a catalyst material extending from the cutting edge to a depth of at least 300 microns, wherein the first layer includes diamond having a diamond average grain size less than 12 microns, wherein the first layer has a higher diamond volume fraction than the second layer, and wherein the protrusion has a height to width ratio of less than 0.5 and the protrusion is rounded.
