METHODS AND SYSTEMS FOR REMOVING INTERSTITIAL MATERIAL FROM SUPERABRASIVE MATERIALS OF CUTTING ELEMENTS USING ENERGY BEAMS |
摘要 |
A method of forming a cutting element for an earth-boring tool may include directing at least one energy beam at a surface of a volume of polycrystalline superabrasive material including interstitial material disposed in regions between inter-bonded grains of polycrystalline superabrasive material. The method includes ablating the interstitial material with the at least one energy beam such that at least a portion of the interstitial material is removed from a first region of the volume of polycrystalline superabrasive material without any substantial degradation of the inter-bonded grains of superabrasive material or of bonds thereof in the first region. |
