Document Type and Number:
Japanese Patent JPS5393495
Kind Code:
A
Abstract:
A metal bonded abrasive body comprising diamond or cubic boron nitride abrasive particles held in a metal bonding matrix, the metal bonding matrix consisting of cobalt, present in an amount of at least 50 percent by weight of the matrix, and boron in the form of cobalt borides substantially uniformly distributed through the matrix. The invention also provides for a method of producing such bodies which includes mixing cobalt or a cobalt alloy, in powder form, with diamond or cubic boron nitride particles and sintering the mixture to produce the body and is characterized in that the cobalt or alloy powder is mixed with a boriding powder and sintered at a temperature of 800 DEG C. to 1000 DEG C. to boride the cobalt, the boriding taking place before or during the body-forming sintering step.
