摘要：
Polycrystalline diamond cutters (500, 520, 540, 560) and methods of making thereof are described, the cutters including a substrate (502, 522, 542, 562), and a diamond body (501, 521, 541, 561), the diamond body including 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 (405, 428, 449) have lower average sizes or average diameters comparative to a majority of diamond particles in a second region (406, 429, 448).
