In accordance with the present invention, a method for manufacturing tungsten carbide components is provided. The method includes forming a composite material out of tungsten carbide powder and binder powder, pressing the composite material into a plurality of components, heating the plurality of components, optionally under pressure, to liquefy the binder, cooling the plurality of components until the binder solidifies, optionally grinding each of the plurality of components to a desired size, and cascading the plurality of components in a cascading machine under high energy conditions.

La présente invention a trait à un procédé pour la fabrication de composants de carbure de tungstène. Le procédé comprend le formage d'un matériau composite à partir de poudre de carbure de tungstène et de poudre liante, la formation par compression du matériau composite en une pluralité de composants, le réchauffage de la pluralité de composants, éventuellement sous pression, en vue de liquéfier le liant, le refroidissement de la pluralité de composants jusqu'à solidification du liant, éventuellement le meulage de chacun de la pluralité de composants à une taille souhaitée et le broyage de la pluralité de composants dans une machine de broyage dans des conditions de haute énergie.
