Improved sweep through process for making polycrystalline compacts. |
摘要 |
<p>The conventional high pressure/high temperature catalyst sweep through process for making diamond and cubic boron nitride compacts is modified by adding an intermediate metal or metal alloy, which has a melting point below that of the catalyst (e.g. cobalt), is miscible with the catalyst, and preferably sweeps through the mass of abrasive crystals first, whereby there is reduced flaw formation in such compacts.</p> |
