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.

Structured abrasive articles and methods of making the same

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.
