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.

Abstract: An abrasive article configured to grind a workpiece having a fracture toughness of at least about 5.5 MPa•m 0.5 may include a body comprising abrasive particles contained within a bond material comprising a metal, wherein the body comprises a ratio of V AG /V BM of at least about 1.3, wherein V AG is a volume percent of abrasive particles within a total volume of the body and V BM is a volume percent of bond material within the total volume of the body, and wherein the abrasive particles have an average particle size of at least about 1 micron and not greater than about 20 microns.
