    摘要: A method for making polycrystalline superhard material comprises providing an electrically conductive substrate defining at least one deposition surface, electrophoretically depositing charged superhard particles or grains on to the deposition surface(s) of the substrate to form a pre-sinter body, and subjecting the pre-sinter body to a temperature and pressure at which the superhard material is thermodynamically stable, sintering and forming polycrystalline superhard material. There is also disclosed a superhard wear element comprising a polycrystalline superhard material produced by such a method.
