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.
La présente invention concerne un corps abrasif à matrice de métal de fusion et un procédé de préparation dudit corps. Le corps abrasif à matrice de métal de fusion comprend une pluralité de particules abrasives enrobées de métal et une matrice de métal de fusion comprenant un métal liant et une quantité efficace d'un métal capteur d'oxygène. Les particules enrobées de métal sont réparties dans la matrice de métal de fusion qui lie les particules abrasives ensemble. Le métal capteur d'oxygène agit comme un inhibiteur d'oxygène (c'est-à-dire qu'il </= piège >/= l'oxygène), protégeant ainsi de l'oxydation l'enrobage métallique favorisant l'adhérence sur la particule abrasive.
