Sintering of thick solid carbonate-based PCD for drilling application |
摘要 |
A method of making a polycrystalline diamond compact includes forming multiple layers of premised diamond particles and carbonate material, where the carbonate material includes an alkaline earth metal, carbonate, and where each layer has a weight percent ratio of diamond to carbonate that is different from adjacent layers. The layers are subjected to high pressure high temperature conditions to form polycrystalline diamond. |
