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.
Claims31
An abrasive article comprising:
- a substrate;
- a plurality of bodies attached to the substrate, the plurality of bodies comprises a plurality of pores having a D90 of not greater than 10 microns, and wherein the plurality of bodies comprises a normalized Porosity Content Variation (PCV) value of not greater than 1.3;
- and
- wherein each body of the plurality of bodies comprises abrasive particles contained in a bond material including a vitreous material.
An abrasive article comprising:
- a substrate;
- a plurality of bodies attached to the substrate, the plurality of bodies comprises a plurality of pores defining a pore size distribution having a 10th percentile value (D10), and wherein the distance between the 10th percentile (D10) and an average pore size (D50) is not greater than 1 micron, and wherein the plurality of bodies comprises a normalized Porosity Content Variation (PCV) value of not greater than 1.3;
- and
- wherein each body of the plurality of bodies comprises abrasive particles contained in a bond material including a vitreous material.
