Abstract
Metal carbide supported polycrystalline diamond (PCD) compacts having improved abrasion/impact resistance properties and a method for making the same under high temperature/high pressure (HT/HP) processing conditions. The PCD compact is characterized as having a mixture of submicron sized diamond particles and large sized diamond particles.
Claims10
A metal carbide supported polycrystalline diamond (PCD) compact comprising:
- a sintered PCD compact layer;
- and
- a cemented metal carbide support layer bonded to said PCD compact layer, said cemented metal carbide support layer comprising particles of a metal carbide;
- wherein said sintered PCD compact layer is characterized as having a mixture of submicron sized diamond particles having particle sizes ranging from about 0.01 to about 1 micron and large sized diamond particles having particle sizes ranging from about 6 to about 100 microns;
- and
- wherein said sintered PCD compact layer comprises from about 2 to about 15 weight percent submicron sized diamond particles.
3 more elements
The metal carbide supported PCD compact of 1, wherein the large sized diamond particles have particle sizes ranging from about 10 to about 100 microns.
