摘要
Polycrystalline diamond cutters and methods of making thereof are described. The cutters include a substrate and a diamond body. The diamond body includes diamond particles spatially arranged according to a gradient of particle sizes. The methods include steps of suspending diamond particles in a liquid and allowing their sedimentation according to a gradient of particle sizes resulting in regions spatially arranged axially and/or radially in which a majority of diamond particles in one region have lower average sizes or average diameters comparative to a majority of diamond particles in a second region.
