Abstract
An abrasive article, such as a structured abrasive article, can be treated by subjecting it to plasma whereby the outer surface can be eroded exposing at least a portion of the abrasive particles dispersed within a cross-linked binder forming the abrasive composites. Depending on the process conditions for the plasma treatment, it is possible to erode only a small portion or substantially all of the cross-linked binder from the outer surface. Thus, the initial cut-rate of the abrasive article can be controlled since it is possible to precisely control the degree, height, or area of the exposed abrasive particles.
