Abstract
An abrasive article includes a body having abrasive grains contained within a bond material comprising a metal or metal alloy, wherein the body comprises a ratio of VAG/VBM of at least about 1.3, wherein VAG is the volume percent of abrasive grains within the total volume of the body and VBM is the volume percent of bond material within the total volume of the body.
Claims17
An abrasive article comprising:
- a bonded abrasive body comprising a particulate material contained within a bond material comprising a metal or metal alloy;
- an active bond composition with the bond material, and
- a porosity of at least about 18 vol. % for a total volume of the bonded abrasive body,
- wherein the particulate material comprises abrasive grains,
- wherein the bonded abrasive body comprises a content of abrasive grains of at least 40 vol % for a total volume of the bonded abrasive body,
- wherein the bond material comprises a bond phase,
- wherein the active bond composition comprises a precipitated phase and an interfacial phase,
- wherein the interfacial phase is disposed at an interface between the particulate material and the bond material,
- wherein the precipitated phase is dispersed throughout the bond material and is a distinct phase from the interfacial phase, and
- wherein the precipitated phase comprises a composition including at least one element of an active bond composition and at least one element of the bond material.
