Corrosion resistant abrasive article and method of making

摘要

An abrasive article (2) includes a plurality of abrasive particles (6) securely affixed to a substrate (4) with a corrosion resistant matrix material (8). The matrix material (8) includes a sintered corrosion resistant powder and brazing alloy. The brazing alloy includes an element which reacts with and forms a chemical bond with the abrasive particles (6), thereby securely holding the abrasive particles (6) in place. A method of forming the abrasive article (2) includes arranging the abrasive particles (6) and matrix material (8), and applying sufficient heat and pressure to the mixture of abrasive particles (6) and matrix material (8) to cause the corrosion resistant powder to sinter, the brazing alloy to flow around, react with, and form chemical bonds with the abrasive particles (6), and allow the brazing alloy to flow through the interstices of the sintered corrosion resistant powder and form an inter-metallic compound therewith.
