Abstract

L'élément porte sur un élément de coupe PDC destiné à être utilisé dans des trépans de forage, où des interstices de filière distants de la surface de travail sont remplis d'un matériau catalyseur et les interstices adjacents à la surface de travail sont sensiblement exempts du matériau catalyseur. Une région intermédiaire entre la partie sensiblement libre et la partie remplie comporte une pluralité de saillies exemptes de catalyseur, à section globalement conique, qui s'effilent vers le bas, s'étendant jusqu'à une deuxième profondeur à partir de la surface de travail plane, de préférence environ 0,5 fois la première profondeur, ou davantage.
