POLYCRYSTALLINE DIAMOND CONSTRUCTION AND METHOD OF MAKING SAME |
摘要 |
A polycrystalline diamond construction comprises diamond grains exhibiting inter-granular bonding and defining a plurality of interstitial regions, and a non-diamond phase at least partially filling a plurality of the interstitial regions to form non-diamond pools. The percentage of non-diamond phase in the total area of a cross-section of the body of polycrystalline diamond material is between around 0 to 5%, and the average nearest neighbour distance between grains of the non-diamond phase is less than around 1.3 microns in an analysed image of a cross-section through the body of polycrystalline material when analysed using an image analysis technique at a magnification of around 1000 and an image area of 1280 by 960 pixels; or is between around 5 to 10%, and the average nearest neighbour distance between grains of the non-diamond phase is less than around 1.04 microns, or is between around 10 to 15%, and the average nearest neighbour distance between grains of the non-diamond phase is less than around 1.04 microns, or is between around 15 to 30%, and the average nearest neighbour distance between grains of the non-diamond phase is less than around 0.8 microns. |

1. A polycrystalline diamond construction comprising a body of polycrystalline diamond material formed of:
a mass of diamond grains exhibiting inter-granular bonding and defining a plurality of interstitial regions therebetween, and a non-diamond phase at least partially filling a plurality of the interstitial regions to form non-diamond pools, the non-diamond pools each having an individual cross-sectional area, wherein the percentage of non-diamond phase in the total area of a cross-section of the body of polycrystalline diamond material is between around 0 to 5%, and the average nearest neighbour distance between grains of the non-diamond phase is less than around 1.3 microns in an analysed image of a cross-section through the body of polycrystalline material when analysed using an image analysis technique at a magnification of around 1000 and an image area of 1280 by 960 pixels. |
