  • Publication number: 20230356360
    Abstract: 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.
    Type: Application

  • Publication number: 20210214596
    Abstract: An abrasive article including a first abrasive body coupled to a substrate, the first abrasive body having abrasive particles including a superabrasive and a bond material including a vitreous material and a second abrasive body coupled to the substrate, the second abrasive body having abrasive particles including a superabrasive and a bond material including at least one non-vitreous phase material, and as wear rate differential between the first abrasive body and second abrasive body of at least 0.08 cc.

  • Publication number: 20210138610
    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.
