Title (EN) METAL BOND ABRASIVE ARTICLE COMPRISING POROUS CERAMIC ABRASIVE COMPOSITES AND METHOD OF USING SAME TO ABRADE A WORKPIECE
(FR) ARTICLE ABRASIF COLLE A UN METAL COMPRENANT DES COMPOSITES ABRASIFS CERAMIQUES POREUX ET PROCEDE D'UTILISATION DE CET ARTICLE POUR ABRASER UNE PIECE
Abstract:
(EN) An abrasive article (40) is provided comprising a rigid backing (42) having a first major surface (44) and a second major surface (46); a plurality of ceramic abrasive composites (50) each comprising a plurality of abrasive particles (51) distributed throughout a porous ceramic matrix (53); and at least one metal coating (52) which affixes the ceramic abrasive composites to at least one major surface of the backing, preferably a series of metal coatings (48, 52a, 52b). The present invention also provides a method of abrading a workpiece using an abrasive artcile of the present invention, the method comprising the steps of: (a) contacting a surface of a workpiece with an abrasive article of the present invention (b) applying a liquid at an interface between the workpiece and the abrasive article; and (c) moving the workpiece and the abrasive article relative to one another.
(FR) L'invention concerne un article abrasif comprenant une feuille de support rigide ayant une première surface principale et une seconde surface principale; une pluralité de composites abrasifs céramiques, chacun comprenant une pluralité de particules abrasives réparties sur une matrice céramique poreuse; et au moins un revêtement métallique qui fixe les composites abrasifs céramiques à au moins une surface principale de la feuille de support.
