FUSED ABRASIVE BODIES COMPRISING AN OXYGEN SCAVENGER METAL

摘要

A fused metal matrix abrasive body and method of preparing a fused metal matrix abrasive body is provided. The fused metal matrix abrasive body comprises a plurality of metal coated abrasive particles and a fused metal matrix comprising a bond metal and an effective amount of an oxygen scavenger metal. The metal coated abrasive particles are distributed in the fused metal matrix which bonds the abrasive particles together. The oxygen scavenger metal functions as a scavenger (i.e., "getter") for oxygen thereby protecting the adhesion promoting metal coating on the abrasive particle from the oxidation.
