Title (EN) POLYCRYSTALLINE DIAMOND COMPACT WITH INCREASED LEACHING SURFACE AREA AND METHOD OF LEACHING A POLYCRYSTALLINE DIAMOND COMPACT
(FR) COMPRIMÉ DE DIAMANT POLYCRISTALLIN PRÉSENTANT UNE SURFACE DE LIXIVIATION ACCRUE ET PROCÉDÉ DE LIXIVIATION D'UN COMPRIMÉ DE DIAMANT POLYCRISTALLIN
Abstract: front page image
(EN)The present disclosure provides a sintering assembly and a polycrystalline diamond compact (PDC) including a acid-labile leach-enhancing material, a PDC including cavities formed by removal of an acid-labile leach-enhancing material, and a method of forming a leached PDC using an acid-labile leach-enhancing material. The present disclosure further includes drill bits using PDCs formed suing an acid-labile leach-enhancing material.
(FR)La présente invention concerne un ensemble de frittage et un comprimé de diamant polycristallin (PDC) comprenant un matériau d'amélioration de lixiviation labile en milieu acide, un PDC comprenant des cavités formées par élimination d'un matériau d'amélioration de lixiviation labile en milieu acide, et un procédé de formation d'un PDC lixivié à l'aide d'un matériau d'amélioration de lixiviation labile en milieu acide. La présente invention concerne en outre des trépans utilisant des PDC formés à partir d'un matériau d'amélioration de lixiviation labile en milieu acide.
