摘要： A bonded abrasive article suitable for processing hard materials such as sapphire. In an embodiment, an abrasive article includes a bonded abrasive body including a bond material comprising a metal, abrasive particles contained within the bond material having an average particle size of not greater than about 20 μm, and a pore size standard deviation of not greater than about 16 μm. An abrasive article can also include a bonded abrasive body having a bond material comprising metal, abrasive particles contained within the bond material having an average particle size of not greater than about 20 μm, and an average pore size of not greater than about 110 μm.

摘要： 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.

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.
