A method of making a thermally-stable cutting element |
| abstract |
A method is disclosed for making a thermally stable diamond cutting element which includes forming an acid mixture containing two different acid species by combining an acid solution and at least one acid-forming compound, wherein the at least one acid-forming compound is provided in solid form, and wherein the at least one acid-forming compound produces an acid that is different than the acid solution; treating at least a portion of a sintered diamond body by placing the sintered diamond body in the acid mixture in order to leach infiltrated metal (catalyst) from the interstitial spaces. The acid mixture may be formed form nitric acid and ammonium bifluoride (ammonium hydrogen fluoride). The temperature and pressure of the leaching process may be controlled, for example in a pressure vessel 20. The metal-depleted sintered diamond body may be attached to a variety of support structures to form cutting elements. |
