Abstract
A method of making a polycrystalline diamond cutter element includes forming a blend, comprising a first particle size of polycrystalline diamond particles and a second particle size of polycrystalline diamond particles; forming a suspension of nanocrystalline diamond particles suspended in a solvent; and mixing the blend into the suspension to form a polycrystalline diamond mixture comprising nanocrystalline diamond coated polycrystalline diamond particles. The mixture is sintered with a substrate at high temperature and high pressure to form the polycrystalline diamond cutter element.
