  • Article of superabrasive coated with metal
    Patent number: 6663682
    Abstract: A process for metal coating diamond superabrasive particles involves heating the superabrasive particles in the presence of coat-forming powder of a metal compound under a common inert atmosphere. The metal compound contains a metal which can be thermochemically reduced by the superabrasive substance serving as the reducing agent. The process forms a chemical bond at the interface between the outer metal layer and the superabrasive particle substrate. The metal coated superabrasive particles can be hydrogen treated in situ and separated from excess coat-forming powder easily by filtration. The product particles are ideal for use in a wide variety of metal bonded cutting, machining, dressing and other abrasive tools, especially diamond film insert and single layer diamond tools.
