Methods of forming cutting elements by removing metal from interstitial spaces in polycrystalline diamond |
| abstract |
Methods of forming a cutting element include immersing at least a portion of a volume of polycrystalline diamond in a liquid electrolytic solution, applying a voltage between the polycrystalline diamond and a cathode in contact with the liquid electrolytic solution, and removing at least a portion of metal catalyst from interstitial spaces between adjacent diamond grains. The polycrystalline diamond includes interbonded diamond grains and metal catalyst particles in the interstitial spaces between adjacent grains of polycrystalline diamond material. Some methods include forming a barrier over a portion of a volume of polycrystalline diamond and transferring at least a portion of the metal catalyst from a portion of the polycrystalline diamond not covered by the barrier to a liquid electrolyte. Some methods include encapsulating a volume of polycrystalline diamond in a barrier and selectively removing a portion of the barrier from a first portion of the volume of polycrystalline diamond. |
