    摘要： A cutting element for an earth-boring tool includes a substrate and a volume of superabrasive material disposed on a substrate. The volume of superabrasive material has an exposed outer surface with a non-planar geometry. The cutting element is configured to be located and oriented on an earth-boring tool so as to remove subterranean earth formation material by compressing and fracturing or plastically deforming the formation material with at least a portion of the exposed outer surface of the volume of superabrasive material during use of the earth-boring tool in an earth-boring operation. The exposed outer surface of the volume of superabrasive material includes a first area having a first average surface finish roughness and a second area having a second average surface finish roughness greater than the first average surface finish roughness. Earth-boring tools carrying such cutting elements and methods of forming such earth-boring tools are also disclosed.

    摘要： A cutting element for an earth-boring tool includes a volume of superabrasive material having a cutting face and a shaped feature on the cutting face. The shaped feature may include at least one of a recess extending into the volume of superabrasive material from the cutting face and a protrusion extending outward from the cutting face. A first portion of the cutting face may have a first surface roughness, and a second portion of the cutting face may have a second surface roughness greater than the first surface roughness of the first portion of the cutting face. The volume of superabrasive material may be disposed on a substrate. Methods of forming cutting elements may include forming one or more shaped features in a cutting face of the cutting elements. Earth-boring tools may include such cutting elements.

    摘要： A method of making shaped abrasive particles including forming an abrasive flake comprising a plurality of precursor shaped abrasive particles and a frangible support joining the precursor shaped abrasive particles together; transporting the abrasive flake through a rotary kiln to sinter the abrasive flake; and breaking the sintered abrasive flake into individual shaped abrasive particles. The method is useful to make small shaped abrasive particles having insufficient mass to be efficiently individually sintered in a rotary kiln without joining two or more of the shaped abrasive particles together.

    摘要： In various embodiments, a polycrystalline diamond compact (“PDC”) comprises a substrate including an interfacial surface having a raised region. The PDC comprises a polycrystalline diamond (“PCD”) table bonded to the interfacial surface of the substrate. The PCD table defines an upper surface and exhibits a thickness over the raised region. The PCD table includes a plurality of bonded diamond grains defining a plurality of interstitial regions. A first region of the PCD table adjacent to the substrate includes metal-solvent catalyst disposed interstitially between the bonded diamond grains thereof, and a leached second region of the PCD table extends inwardly from the upper surface. The interstitial regions of the leached second region are depleted of metal-solvent catalyst. The geometry of the PCD table and raised region may be selected so that residual compressive stresses therein are retained to a sufficient level after leaching to provide a damage tolerant/thermally-stable PCD table.
