摘要： An abrasive article can include a body including a bond material, abrasive particles, and a plurality of pores, wherein the bond material can comprise a vitreous material. In one embodiment, an average particle size of the abrasive particles can be between 0.1 microns to 5 microns, and a porosity of the body may be between 40 vol % to 70 vol %, wherein the porosity may define an average pore size (D50) of at least 0.1 microns and not greater than 5 microns.

摘要： 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.

摘要： An abrasive article can include a body including a bond material comprising an inorganic material, abrasive particles and a filler comprising a nitride. The filler comprising a nitride can compensate shrinkage of the body during sintering while maintaining required strength and wear properties of the body.
