Title (EN) INFILTRATION METHODS FOR FORMING DRILL BITS
(FR) PROCÉDÉS D'INFILTRATION POUR FAÇONNER DES FORETS
Abstract:
(EN) An infiltration method of forming an article including providing a working mold including a solid binder member extending through an interior of the working mold, wherein the solid binder member is made of a binder material, and providing a layer of powder matrix material within a molding void of the working mold. The method further includes heating the working mold to form a molten binder pathway from the solid binder member to infiltrate the layer of powder matrix material.
(FR) L'invention porte sur un procédé d'infiltration pour le façonnage d'un article comportant les opérations consistant à prévoir un moule de travail comprenant un élément liant solide s'étendant à travers un intérieur du moule de travail, l'élément liant solide étant fait d'une matière liante, et à disposer une couche de matière de matrice pulvérulente à l'intérieur d'une cavité de moulage du moule de travail. Le procédé comporte en outre l'opération consistant à chauffer le moule de travail pour former un trajet de liant fondu à partir de l'élément liant solide, pour infiltrer la couche de matière de matrice pulvérulente.
