TECHNIQUES FOR AFFECTING LEACHING PROFILES IN CUTTING ELEMENTS FOR EARTH-BORING TOOLS AND RELATED CUTTING ELEMENTS, EARTH-BORING TOOLS, AND METHODS

Cutting elements for earth-boring tools may include a cutting table secured to a substrate. The cutting table may include a first region at least substantially free of an infiltrant, a second region comprising the infiltrant, and a passageway extending from an exterior partially through the first region. A distance between the exterior and a boundary between the first region and the second region, as measured from a major surface of the cutting table, may not be constant. Methods of making cutting elements for earth-boring tools may involve placing a sacrificial material among grains of a superabrasive material. The grains of the superabrasive material and the sacrificial material may be exposed to elevated temperature and pressure in a presence of a catalyst material to form a cutting table. The sacrificial material and a portion of the catalyst material may be removed from a first region of the cutting table.
