Abstract
An abrasive article includes a plurality of abrasive particles securely affixed to a substrate with a corrosion resistant matrix material. The matrix material includes a sintered corrosion resistant powder and a brazing alloy. The brazing alloy includes an element which reacts with and forms a chemical bond with the abrasive particles, thereby securely holding the abrasive particles in place. A method of forming the abrasive article includes arranging the abrasive particles in the matrix material, and applying sufficient heat and pressure to the mixture of abrasive particles and matrix material to cause the corrosion resistant powder to sinter, the brazing alloy to flow around, react with, and form chemical bonds with the abrasive particles, and allow the brazing alloy to flow through the interstices of the sintered corrosion resistant powder and form an inter-metallic compound therewith.
