摘要 |
Embodiments relate to rotary drill bits that employ superabrasive cutting elements including a diamond-silicon carbide composite table. In an embodiment, a rotary drill bit includes a bit body configured to engage a subterranean formation. The bit body includes a plurality of blades. The rotary drill bit further includes a plurality of superabrasive cutting elements. Each of the superabrasive cutting elements is attached to a corresponding one of the cutting blades. At least one of the superabrasive cutting elements includes a substrate and a superabrasive table bonded to the substrate. The superabrasive table comprises diamond-silicon carbide composite including a matrix comprising nanometer-sized silicon carbide grains and micrometer-sized diamond grains dispersed through the matrix.
