Abstract

Cutting elements for earth-boring tools may include a substrate and a polycrystalline superabrasive material secured to the substrate. The polycrystalline superabrasive material may include a first region including catalyst material in interstitial spaces among interbonded grains of the polycrystalline superabrasive material. A second region at least substantially free of catalyst material in the interstitial spaces among the interbonded grains of the polycrystalline superabrasive material may be located adjacent to the first region. An undulating boundary defined between the first region and the second region may include bumps and dimples formed by crests and troughs of a repeating pattern of concentric circles encircling a longitudinal axis of the cutting element.
