Abstract
A method of forming a metal deposit on an ultra-hard material. In an embodiment, the method includes providing a plurality of ultra-hard particles, mixing the ultra-hard particles in a solution with a metal salt, drying the solution to create a mixture of metal salt particles adhered to surfaces of the ultra-hard particles, heating the mixture to convert the metal salt particles into metal deposits on the surfaces of the ultra-hard particles, and HTHP sintering the mixture of ultra-hard particles with the metal deposits to form a polycrystalline ultra-hard material.
