Abstract
An abrasive article can include a substrate, abrasive particles coupled by a bond material to the substrate, and a coating overlying at least partially the exterior surface of the bond material. The coating can be a poly(p-xylylene) polymer applied via vapor deposition and may provide enhanced strength to the bond material and extended life time to the abrasive article.
