Abstract
A bonded abrasive article can include a body including a bond material, abrasive particles contained within the bond material, and pores contained within the body. At least a portion of the pores of the body can include a coating. In one aspect, the coating can be a poly(p-xylylene) polymer applied via vapor deposition. The coated abrasive body can maintain a high permeability and pore volume after coating, and the coating can provide an increase in flexural strength and corrosion resistance to the abrasive article, thereby greatly enhancing its life time.
