POLYCRYSTALLINE DIAMOND |
| 摘要 |
A PCD body comprises a skeletal mass of inter-bonded diamond grains defining interstices between them. At least some of the interstices contain a filler material comprising a metal catalyst material for diamond, the filler material containing Ti, W and an additional element M selected from the group consisting of V, Y, Nb, Hf, Mo, Ta, Zr Cr, Zr and the rare earth elements. The content of Ti within the filler material is at least 0.1 weight % and at most 20 weight %. The content of M within the filler material is at least 0.1 weight % and at most 20 weight %, and the content of W within the filler material is at least 5 weight % and at most 50 weight % of the filler material. |

1. A PCD body comprising a skeletal mass of inter-bonded diamond grains defining interstices between them, at least some of the interstices containing a filler material comprising a metal catalyst material for diamond, the filler material containing Ti, W and an additional metal M selected from the group consisting of V, Y, Nb, Hf, Mo, Ta, Cr, Zr and the rare earth elements; the content of Ti within the filler material being at least about 0.1 weight % and at most about 20 weight %; the content of M within the filler material being at least about 0.1 weight % and at most about 20 weight %; and the content of W within the filler material being at least about 5 weight % and at most about 50 weight % of the filler material. |
