Abstract
In one or more embodiments, a method includes selecting a cemented carbide substrate from a plurality of cemented carbide substrates in a substrate inventory. Each of the plurality of cemented carbide substrates have a substantially planar top surface. The method also includes emitting a plurality of laser pulses from a laser towards at least the substantially planar top surface of the cemented carbide substrate to ablate selected regions of the cemented carbide substrate thereby forming the cemented carbide substrate into a selected shape.
Claims21
A method, comprising:
- laser ablating selected regions of a cemented carbide substrate, thereby forming the cemented carbide substrate into a selected shape;
- after laser ablating selected regions of the cemented carbide substrate:
- enclosing a plurality of diamond particles and the cemented carbide substrate in a pressure transmitting medium to form a cell assembly;
- and
- subjecting the cell assembly to a temperature of at least about 1000° C. and a pressure in the pressure transmitting medium of at least about 4 GPa to infiltrate the plurality of diamond particles with a portion of a metal-solvent catalyst of the cemented carbide substrate and catalyze formation of a polycrystalline diamond table that is bonded to the cemented carbide substrate.
