Abstract

La présente invention concerne un matériau abrasif (50) qui comprend une pluralité de formes pyramidales s'étendant en saillies d'une surface de base, les saillies (52) étant formées du même matériau, chaque saillie (52) présentant une base pratiquement triangulaire, carrée ou polygonale et des côtés triangulaires qui se rencontrent en un sommet pour pratiquement former un point. Les saillies (52) présentent une combinaison d'arêtes coupantes et de plans dans une configuration telle que le matériau (50) reste abrasif quel que soit le sens d'utilisation. Un revêtement (56) est appliqué afin d'améliorer les performances abrasives et de réduire la porosité de surface. La présente invention concerne aussi un procédé de production du matériau abrasif (50).
