Abstract: According to one embodiment, a method of making an abrasive article is disclosed. The method can comprise: disposing a layer of a curable composition into a mold having a circular mold cavity with a central hub, wherein the circular mold cavity has an outer circumference and a rotational axis extending through the central hub, and wherein the curable composition is comprised of at least some magnetizable abrasive particles dispersed therein; and varying a magnetic field relative to the curable composition such that a majority of the magnetizable abrasive particles are at least one of oriented and aligned in a non-random manner relative to a surface of the mold; and at least partially curing the curable composition to provide the bonded abrasive article.

Abstract: A structured abrasive article comprises a plurality of shaped abrasive composites disposed on and secured to a major surface of a backing. The shaped abrasive composites comprise magnetizable abrasive particles retained in an organic binder. On a respective basis, each of the magnetizable abrasive particles has a ceramic body with a magnetizable layer disposed on at least a portion thereof. Methods of making and using the structured abrasive articles are also disclosed.

Abstract: According to one embodiment, a method of making an abrasive article is disclosed. The method can comprise: providing a surface; disposing magnetizable abrasive particles on the surface; and varying a magnetic field relative to the magnetizable abrasive particles to impart a non-random orientation and/or alignment to the magnetizable abrasive particles relative to the surface.

Abstract: Magnetizable agglomerate abrasive particle can comprise constituent abrasive particles retained in a binder material. The magnetizable particles and the constituent abrasive particles are unassociated, and wherein the magnetizable particles have a Mohs hardness of 6 or less. Magnetizable agglomerate abrasive particles can also comprise magnetizable abrasive particles retained in a binder material, wherein each magnetizable abrasive particle comprises a respective ceramic body and a magnetizable layer disposed on at least a portion of the ceramic body. Pluralities of abrasive particles are also disclosed. Methods of making, and abrasive articles including the magnetizable agglomerate particles are also disclosed.
