Abstract
An abrasive article can include a body including a bond material and abrasive particles contained within the bond material. The abrasive particles can include nanocrystalline alumina. The bond material can include an organic material. In an embodiment, the nanocrystalline alumina may have an average crystallite size of not greater than 1.5 microns. In another embodiment, the bond material and the abrasive particles may be mixed and the mixture may cure to form the abrasive article of embodiments herein.
Claims20
An abrasive article comprising:
- a body including:
- a bond material in a content of 5 vol % to 55 vol % for a total volume of the body, wherein the bond material comprises an organic material;
- abrasive particles contained within the bond material, wherein the abrasive particles are in a content of 6 vol % to 65 vol % for the total volume of the body, wherein the abrasive particles comprises nanocrystalline alumina having an average crystallite size of at least 0.01 microns and not greater than 0.16 microns;
- and
- a porosity of 8 vol % to 70 vol % for the total volume of the body.
A method of forming an abrasive article comprising:
