POLYCRYSTALLINE DIAMOND COMPOSITES |
摘要 |
<p>A method of producing a PCD body includes the step of providing a region of coarser diamond particles between a source of binder phase and a region of fine grained diamond particles having a particle size less than 2μm. The binder phase is caused to infiltrate the diamond mass through the region of coarser diamond particles under elevated temperature and pressure conditions suitable to produce PCD. The invention further provides for a PCD diamond composite manufactured by the method of the invention wherein the PCD body is substantially free of abnormal diamond growth.</p> |
