摘要： Polycrystalline compact tables for cutting elements include regions of grains of super hard material. One region of grains (“first grains”) and another region of grains (“second grains”) have different properties, such as different average grain sizes, different super hard material volume densities, or both. The region of first grains and the region of second grains adjoin one another at grain interfaces that may include a curved portion in a vertical cross-section of the table. In some embodiments, discrete regions of the first grains may be vertically disposed between discrete regions of the second grains. As such, the tables have ordered grain regions of different properties that may inhibit delamination and crack propagation through the table when used in conjunction with a cutting element. Methods of forming the tables include forming the regions and subjecting the grains to a high-pressure, high-temperature process to sinter the grains.

摘要： An earth-boring tool includes a body comprising a pocket in a leading end thereof for accepting at least a portion of a bearing element assembly. A bearing element assembly may be disposed within the pocket, and the bearing element assembly may include a retaining element at least partially disposed in a groove in a sidewall of the pocket and a bearing element. The bearing element may include a distal end having a bearing surface, a proximal end, and a side surface between the distal end and the proximal end, the side surface comprising a feature configured to abut the retaining element, wherein mechanical interference between the feature and the retaining element axially retains the bearing element within the pocket. Methods include disengaging a mechanical retention device retaining a bearing element within a pocket in a body of the earth-boring tool, and removing the bearing element from the pocket.

摘要： An earth-boring tool having at least one cutting element with a multi-friction cutting face provides for the steering of formation cuttings as the cuttings slide across the cutting face. The multi-friction cutting element includes a diamond table bonded to a substrate of superabrasive material. The diamond table has a cutting face formed thereon with a cutting edge extending along a periphery of the cutting face. The cutting face has a first area having an average surface finish roughness less than an average surface finish roughness of a second area of the cutting face, the two areas separated by a boundary having a proximal end proximate a tool crown and a distal end remote from the tool crown.

摘要： Cutting elements for earth-boring tools may comprise a substrate, a polycrystalline table comprising superhard material secured to the substrate at an end of the substrate, and a non-planar interface defined between the polycrystalline table and the substrate. The non-planar interface may comprise a cross-shaped groove extending into one of the substrate and the polycrystalline table and L-shaped grooves extending into the other of the substrate and the polycrystalline table proximate corners of the cross-shaped groove. Transitions between surfaces defining the non-planar interface may be rounded. Methods of forming cutting elements for earth-boring tools may comprise forming a substrate to have a non-planar end. The non-planar end of the substrate may be provided adjacent particles of superhard material to impart an inverse shape to the particles. The particles may be sintered to form a polycrystalline table, with a non-planar interface defined between the substrate and the polycrystalline table.
