Abstract
Official abstract text for this publication.
A functional abrasive particle comprises a ceramic body having at least one hole extending therethrough. A functional material is at least partially disposed within the hole. The functional material contains a binder and functional particles that are magnetizable, metallic, or both. Methods of making functional abrasive particles, and abrasive articles including them are also disclosed.
First claim
Opening claim text (preview).
What is claimed is: 1. A functional abrasive particle comprising a ceramic body having at least one hole extending therethrough, and a functional material at least partially disposed within the at least one hole, wherein the functional material comprises a first binder retaining a plurality of functional particles that are magnetizable, metallic, or a combination thereof. 2. The functional abrasive particle of claim 1 , wherein the ceramic body comprises a shaped ceramic body. 3. The functional abrasive particle of claim 2 , wherein the shaped ceramic body comprises a precisely-shaped ceramic body. 4. The functional abrasive particle of claim 1 , wherein the ceramic body comprises a platelet having first and second opposed major facets connected to each other by a plurality of side facets, and wherein each one of said at least one hole extends from the first major facet to the second major facet. 5. The functional abrasive particle of claim 4 , wherein the functional material completely fills the at least one hole. 6. The functional abrasive particle of claim 1 , wherein the functional particles are magnetizable. 7. The functional abrasive particle of claim 6 , wherein the functional particles comprise an alloy of iron, silicon, and aluminum. 8. The functional abrasive particle of claim 1 , wherein the functional particles are metallic. 9. The functional abrasive particle of claim 1 , wherein the first binder comprises an organic binder. 10. A plurality of functional abrasive particles according to claim 1 . 11. An abrasive article comprising a plurality of abrasive particles retained in a second binder, wherein at least a majority of the abrasive particles comprise functional abrasive particles according to claim 1 . 12. An abrasive article according to claim 11 , wherein the abrasive article comprises a bonded abrasive wheel. 13. An abrasive article according to claim 11 , wherein the abrasive article comprises a coated abrasive article, wherein the coated abrasive article comprises an abrasive layer disposed on a backing, and wherein the abrasive layer comprises the second binder and the plurality of abrasive particles. 14. An abrasive article according to claim 11 , wherein the abrasive article comprises a nonwoven abrasive, wherein the nonwoven abrasive comprises a nonwoven fiber web having an abrasive layer disposed on at least a portion thereof, and wherein the abrasive layer comprises the binder material and the plurality of abrasive particles. 15. An abrasive article according to claim 11 , wherein most of the functional abrasive particles are aligned parallel to each other.
