The present inventions is directed to a method of polishing a workpiece. The method comprises providing an abrasive article, the abrasive article comprising superabrasive particles within agglomerates. The method then comprises contacting the abrasive article with a workpiece outer surface, the workpiece outer surface comprising a thermal spray hard phase, and relatively moving the abrasive article and the workpiece. The workpiece outer surface may further comprises a bonding phase. The abrasive article may be a continuous belt, an abrasive tape or a resin bonded disk.

Abrasive article with agglomerates and method of use

The present invention relates to a method and apparatus for abrading a workpiece. The apparatus includes an abrasive tape having a microstructured surface on the back face thereof, and a support shoe having a microstructured surface on an exposed pressure face. The two microstructured surfaces intermesh and resist displacement of the abrasive tape with respect to the pressure face as the workpiece is rotatively abraded.
