Abstract
Composite compacts comprising a cluster of abrasive particles selected from among diamond, cubic boron nitride and wurtzite boron nitride on a support medium, are securely bonded to metal tool parts by a process comprising providing a bond initiator between, and in contact with, a surface of the composite compact and a surface of the tool part, passing a short duration, high electrical current pulse through the contacting surfaces sufficient to cause melting of the bond initiator without raising the temperature of the abrasive particles to their decomposition temperature, forcing the composite compact and tool part together under an applied magnetic force pulse while the bond initiator is molten, and recovering the article.
