Title
(EN) ABRASIVE ARTICLE COMPRISING AGGLOMERATES AND METHOD OF MAKING THEREOF
(FR) ARTICLE ABRASIF COMPRENANT DES AGGLOMÉRATS ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN)
The invention relates to an abrasive article comprising a carrier body as well as an abrasive layer, wherein the abrasive layer comprises agglomerates with superabrasive particles bound in a first vitrified bond (bond I) as well as a second vitrified bond (bond II) bonding the agglomerates, wherein the hemisphere point of the first vitrified bond is higher or the same than the hemisphere point of the second vitrified bond. The invention also relates to a method of making an abrasive layer for an article according to the invention.
(FR)
Cette invention concerne un article abrasif comprenant un corps de support ainsi qu'une couche abrasive, la couche abrasive comprenant des agglomérats avec des particules super-abrasives liées dans une première liaison vitrifiée (liaison I) ainsi qu'une seconde liaison vitrifiée (liaison II) liant les agglomérats, le point d'hémisphère de la première liaison vitrifiée étant supérieur ou égal au point d'hémisphère de la seconde liaison vitrifiée. L'invention concerne également un procédé de réservation d'une couche abrasive pour un article selon l'invention.
