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 scavenge r metal. The metal coated abrasive particles are distributed in the fused meta l matrix which bonds the abrasive particles together. The oxygen scavenger met al functions as a scavenger (i.e., "getter") for oxygen thereby protecting the adhesion promoting metal coating on the abrasive particle from the oxidation .
