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 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 super hard construction comprises a substrate comprising a peripheral surface, an interface surface and a longitudinal axis extending in a plane and a super hard material layer formed over the substrate and having an exposed outer surface, a peripheral surface extending therefrom and an interface surface. One of the interface surface of the substrate or the interface surface of the super hard material layer comprises one or more projections arranged to project from the interface surface, the one or more projections being spaced from the peripheral surface of the substrate and a peripheral flange extending between the peripheral side edge and the interface surface. The peripheral flange is inclined at an angle of between around 5 degrees to around 30 degrees to a plane substantially perpendicular to the plane through which the longitudinal axis extends.

Abstract

A superhard polycrystalline construction comprises a body of polycrystalline superhard material comprising a structure comprising superhard material, the structure having porosity greater than 20% by volume and up to around 80% by volume. A method of forming such a superhard polycrystalline construction comprises forming a skeleton structure of a first material having a plurality of voids, at least partially filling some or all of the voids with a second material to form a pre-sinter assembly, and treating the pre-sinter assembly to sinter together grains of superhard material to form a body of polycrystalline superhard material comprising a first region of superhard grains, and an interpenetrating second region; the second region being formed of the other of the first or second material that does not comprise the superhard grains; the superhard grains forming a sintered structure having a porosity greater than 20% by volume and up to around 80% by volume.

Abstract

This application describes a method of making a super-hard article that includes a super-hard structure bonded to a substrate. The super-hard structure generally includes a sintered plurality of super-hard grains made from cubic boron nitride. The method generally includes providing raw material powder suitable for sintering the super-hard structure; combining the raw material powder with an organic binder material in a liquid medium to form a paste; providing a substrate assembly having a formation surface area configured for forming a boundary of the super-hard structure, the substrate having a recess coterminous with the formation surface area; extruding the paste into contact with the formation surface area to provide a paste assembly; and heat treating and/or sintering the paste assembly to remove the binder material and provide a pre-sinter assembly.
