CUTTER PROTECTION DURING LEACHING PROCESS |
| 摘要 |
A method of forming a thermally stable cutting element may include providing a cutting element including a substrate fixed to a polycrystalline diamond cutting table; enclosing the substrate and at least a portion of the polycrystalline diamond cutting table within a protective element to form a partially enclosed cutting element; exerting a compressive squeeze on the cutting element of about 5-25%; and exposing the partially enclosed cutting element to a leaching solution so that at least part of an unenclosed portion of the polycrystalline diamond table is in contact with the leaching solution. |

1. A method of treating a cutting element, comprising:
providing a cutting element comprising polycrystalline diamond fixed to a substrate; enclosing the substrate and at least a portion of the polycrystalline diamond within a protective element to form a partially enclosed cutting element; exerting a compressive squeeze on the cutting element of about 5-25%; and exposing the partially enclosed cutting element to a leaching solution so that at least part of an unenclosed portion of the polycrystalline diamond is in contact with the leaching solution. |
