Thermal Degradation and Crack Resistant Functionally Graded Cemented Tungsten Carbide and Polycrystalline Diamond for Metal Machining and Rock Drilling Tools **Value Express**

Patent Abstract A WC—Co material or polycrystalline diamond-Co material that has a gradient in the grain size of the particles. Specifically, the material may have a top layer that has coarse grains that is designed to dissipate the heat caused by friction (and thus prevent thermal cracking). The material will then have a bulk substrate that is...
