Abstract
A cobalt-boron alloy is used as the matrix in a polycrystalline diamond compact. The matrix is hot isostatic pressed with tungsten carbide to form a substrate. The substrate is then high-pressure, high temperature sintered with a diamond powder, preformed and acid-leeched diamond plate, or another ultra-hard material in a press mold to sweep the matrix, thereby creating an ultra-hard polycrystalline compact at a temperature 400° C. lower and with less graphitization than conventional techniques using cobalt binder. The compact is stronger and has a longer useful life than conventional compacts.
