Abrasive article and method of forming

摘要

An abrasive article including a substrate having an elongated body, a tacking layer overlying the substrate, a first type of abrasive particle overlying the tacking layer, a second type of abrasive particle different than the first type of abrasive particles overlying the tacking layer, and a bonding layer overlying at least a portion of one of the first type of abrasive particle and the second type of abrasive particle and the tacking layer.

1. An abrasive article comprising:
a substrate comprising an elongated body having an aspect ratio of length:width of at least about 10:1; a tacking layer overlying the substrate, wherein the tacking layer has a melting point of not greater than about 450° C.; a first type of abrasive particle comprising an agglomerated particle overlying and in contact with the tacking layer, wherein the tacking layer comprises an average thickness of at least about 11% of an average particle size of the first type of abrasive particle; a second type of abrasive particle different than the first type of abrasive particle and comprising an unagglomerated particle overlying and in contact with the tacking layer; and a bonding layer overlying at least a portion of one of the first type of abrasive particle and the second type of abrasive particle and the tacking layer, wherein the tacking layer is bonded to the surface of the substrate at a bonding region defined by an interdiffusion of elements between the tacking layer and the substrate.
