Abstract
An abrasive article can include an abrasive component including a body. The body can include a bond matrix and abrasive particles contained in the bond matrix. In an embodiment, the body can include an interconnected phase extending through at least a portion of the bond matrix. The body can include a discontinuous phase including a plurality of discrete members. At least one of the discrete member can include a macroscopic pore. In another embodiment, the body can include a porosity of at least 15 vol % for a total volume of the body.
Claims20
An abrasive article, comprising an abrasive component including a body, wherein the body comprises:
- a bond matrix including a bond material including a metal material and abrasive particles contained within the bond matrix;
- an interconnected phase extending through at least a portion of the bond matrix including a different metal material than the bond material, wherein the body comprises at least 15 vol % and at most 70 vol % of the interconnected phase for a total volume of the body;
- and
- a discontinuous phase comprising macroscopic pores, wherein the discontinuous phase is distinct from the interconnected phase, the bond material, and the abrasive particles.
An abrasive article, comprising an abrasive component including a body, wherein the body comprises:
- a bond matrix including a bond material including a metal material and abrasive particles contained within the bond matrix, wherein the body comprises at least 8 vol % and at most 50 vol % of abrasive particles for a total volume of the body;
- an interconnected phase extending through at least a portion of the bond matrix including a different metal material than the bond material;
- and
- a porosity comprising discrete macroscopic pores having a pore size of at least 200 microns.
