Abstract

This disclosure relates to a method of making a shaped tool component from a precursor sintered body comprising polycrystalline diamond (PCD). The sintered body has a PCD table joined to a substrate, and the PCD table varies in depth. The resulting shaped tool component thus also has a PCD layer with varying depth. A method of making a shaped tool component comprising polycrystalline diamond (PCD), comprising the steps: h. Adding a diamond feed stock to a refractory cup; i. Adding a p re-shaped cemented carbide body to the refractory cup adjacent the diamond feed stock; j. Compacting the diamond feed stock and cemented carbide body to form a green body; k. Sintering the green body at a temperature between 1400° C. to 2100° C. and at a pressure of at least 7 GPa, for at least 30 seconds to form a sintered PCD precursor body that comprises a PCD table sinter-joined to the cemented carbide substrate at an interface;

Abstract

A sensor system has a cutter element for a cutting tool, an interrogation transceiver operable to transmit a radio-frequency (RF) interrogation signal; and a sensor transceiver system operable to receive the RF interrogation signal and to transmit an RF response signal. The sensor transceiver system includes a signal guide medium configured to transduce between the RF interrogation signal, a guided signal in the signal guide medium, and the RF response signal. A characteristic of the RF response signal is dependent upon a condition of the signal guide medium. The cutter element includes the signal guide medium to allow the condition of the signal guide medium to depend upon a condition of the cutter element proximate the signal guide medium. A method of using the sensor system is also disclosed.

Abstract

A diamond powder comprising diamond particles having an average particle size of no more than 20 μm and a vacancy or impurity-vacancy point defect concentration of at least 1 ppm. At least 70% of the volume of diamond in the powder is formed from a single crystal growth sector. This leads to a substantially uniform concentration of vacancies or impurity-vacancy point defects in the diamond particles because the rate of impurity take-up during growth is heavily dependent on the growth sector, which in turn leads to a more uniform fluorescent response. There is also described a method for making such a powder.

Abstract

A cutter element for an earth-boring tool, comprising a polycrystalline diamond (PCD) volume joined at an interface boundary to a cemented carbide substrate. The PCD volume includes a rake face opposite the interface boundary, an edge of the rake face being suitable as a cutting edge of the cutter element. The PCD volume comprises a plurality of strata directly joined to each other at inter-strata boundaries, in which each of a first plurality of the strata comprises PCD material having a first diamond content; each of a second plurality of the strata comprises PCD material having a second diamond content; the second diamond content being greater than the first diamond content; and the strata of the first and second pluralities disposed in an alternating arrangement with respect to each other. The strata are configured and arranged such that a radial line through the edge and a centroid of the interface boundary intersects, within 1,000 microns from the edge, each of the inter-strata boundaries, and the respective tangent plane to each inter-strata boundary at the respective intersection is disposed relative to the radial line at no less than a minimum angle of 30°.
