Patent ID: 7198553

Claim:
A method of making an abrasive article comprising a substrate having opposite generally planar top and bottom surfaces; and a plurality of abrasive particles arranged on at least a portion of at least one of said top and bottom substrate surfaces and affixed thereto with a matrix material, said matrix material comprising a brazing alloy and a corrosion resistant powder, wherein said corrosion resistant powder comprises from 50% to 99% by weight of said matrix material, said method comprising the steps of: (a) providing the matrix material on the substrate; (b) arranging the abrasive particles in the matrix material, whereby at least a portion of each abrasive particle is embedded in the matrix material; and (c) applying heat and pressure to the matrix material sufficient to cause said brazing alloy to flow, said corrosion resistant powder to be sintered, the brazing alloy to form both a chemical bond and a mechanical attachment with the abrasive particles, and the matrix material and sintered corrosion resistant powder to form an inter-metallic compound at an interface of the matrix material and corrosion resistant powder.
