Abstract
Official abstract text for this publication.
A polycrystalline diamond construction comprising a body of polycrystalline diamond material formed of a mass of diamond grains exhibiting inter-granular bonding, wherein between around 50 wt % to around 99 wt % of the diamond grains in a cross-section of the body of polycrystalline diamond material taken at any orientation have a sectorial growth structure. A method of making the polycrystalline diamond construction is also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polycrystalline diamond construction comprising: a body of polycrystalline diamond material formed of a mass of diamond grains exhibiting inter-growth and inter-granular bonding, wherein between around 50 wt % to around 99 wt % of the diamond grains in a cross-section of the body of polycrystalline diamond material taken at any orientation have a sectorial growth structure. 2. The polycrystalline diamond construction of claim 1 , wherein between around 70 wt % to around 90 wt % of the diamond grains in a cross-section of the body of polycrystalline diamond material taken at any orientation have a sectorial growth structure. 3. The polycrystalline diamond construction of claim 1 , wherein between around 80 wt % to around 90 wt % of the diamond grains in a cross-section of the body of polycrystalline diamond material taken at any orientation have a sectorial growth structure. 4. The polycrystalline diamond construction of claim 1 , wherein the body of polycrystalline diamond material has a thermal conductivity of between 500 W/mK and 800 W/mK. 5. The polycrystalline diamond construction of claim 1 , wherein the body of polycrystalline diamond material is substantially free from plastic deformation. 6. The polycrystalline diamond construction of claim 1 , wherein the body of polycrystalline diamond material is substantially macroscopically stress-free. 7. The polycrystalline diamond construction of claim 1 , wherein the body of polycrystalline diamond material is substantially free from dislocations.
