Abstract
An abrasive article includes a carrier element, an abrasive component, and a bonding region between the abrasive component and the carrier element. The abrasive component includes abrasive particles bound in a metal matrix. The abrasive component further includes a network of interconnected pores substantially filled with an infiltrant. The infiltrant has an infiltrant composition containing at least one metal element. The bonding region includes a bonding metal having a bonding metal composition containing at least one metal element. The bonding region is a region distinct from the carrier element and is a separate phase from the carrier element. An elemental weight percent difference is the absolute value of the difference in weight content of each element contained in the bonding metal composition relative to the infiltrant composition. The elemental weight percent difference between the bonding metal composition and the infiltrant composition does not exceed 20 weight percent.
