Abrasive articles and method of forming same

摘要

An abrasive article including a bonded abrasive body having a bond material made of a vitrified material, abrasive particles comprising a first type of superabrasive material contained in the bond material, a porosity of at least about 50 vol % of the total volume of the bonded abrasive body, and a ΔCTE of not greater than about 5.5 ppm/° C., wherein ΔCTE is defined as a difference between a CTE of the bond material and a CTE of the abrasive particles.

1. An abrasive article comprising:
a bonded abrasive body including:
a bond material comprising a vitrified material;abrasive particles comprising a first type of superabrasive material having a first median particle size; and
a second type of superabrasive material having a second median particle size that is less than the first median particle size;a porosity of at least about 70 vol % and not greater than about 85 vol % of the total volume of the bondedabrasive body, and wherein the bonded abrasive body includes a first content of the first type of superabrasive material and a second content of the second type of superabrasive material, wherein the first content is greater than the second content.
