Abstract:
1. A method for manufacturing a cutting element comprising: subjecting a material comprising a plurality of ultrahard material particles to a first high pressure/high temperature condition to form a sintered ultrahard material body in the substantial absence of a catalyzing material, wherein the ultrahard material body has a material microstructure comprising a matrix phase of bonded together ultrahard material particles and interstitial regions disposed throughout the matrix phase providing a porosity in the range from about 1 to 6 volume percent based on the total volume of the ultrahard material body; removing the ultrahard material body from the first high pressure/high temperature condition; and introducing an infiltrant material into at least a portion of the interstitial regions of the ultrahard material body during a second high pressure/high temperature condition.
