Abstract: A method of reusing a hub in an abrasive assembly is presented that includes removably coupling the abrasive wheel to a reusable hub. The abrasive wheel has an outer circumference and an inner circumference. The abrasive article has an inner circumference and an outer circumference. The method also includes abrading a worksurface by contacting the abrasive wheel to the worksurface. The reusable hub includes a coupling feature configured to directly couple to the abrasive article. The coupling feature includes an adhesive-free connection between the reusable hub and the abrasive wheel. The direct connection is a removable interlocking between the abrasive wheel and the reusable hub.

Abstract: A method of making abrasive particles includes exposing ceramic particles to an organosilane-derived plasma formed from components comprising an organosilane and oxygen to form plasma-modified ceramic particles; and contacting a coupling agent with the second plasma-treated ceramic particle to provide the abrasive particle. Abrasive particles preparable by the method and abrasive particles containing them are also disclosed.
