CA 2288022
The present invention provides an abrasive material (50) comprising a base surface having a plurality of pyramidal shapes protruding therefrom the base surface and the protrusions (52) being formed of the same material, each protrusion (52) having a substantially triangular, square, or polygonal base and triangular sides which meet at an apex which substantially forms a point. The protrusions (52) provide intermixed cutting and planning edges in a pattern such that the material (50) is capable of abrading independent of direction of use. A coating (56) is applied to improve abrasive performance and reduce surface porosity. A method of forming the abrasive material (50) is also provided.
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).
