Document Type and Number:
WIPO Patent Application WO2001004227
Kind Code:
A3
Abstract:
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.
