COMPOSITE DIAMOND ABRASIVE COMPACT |
摘要 |
A composite diamond abrasive compact comprises a diamond compact bonded to a cemented carbide support along a compact/carbide interface and is characterised by the carbide support comprising at least two zones, a first zone containing a binder metal content of a predetermined amount, and a second zone extending from the interface to the first zone and having a binder metal content which is substantially lower than that of the first zone. The second zone has a depth or thickness of no more than 0,75mm. The binder metal content of the second zone increases from the interface to the first zone in a continuous, non-interrupted manner. <IMAGE> |
