COMPOSITE MATERIAL AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/1995/008654

Kind Code:

A1

Abstract:

A composite material based on the product of combustion synthesis and/or heat generation, and an effective process for producing the same. The composite material is essentially (1) a refractory/metal composite material which comprises one or more skeletal structures formed by joining three-dimensionally one or more types of refractory particle selected from among carbides, borides, nitrides and silicides of metals selected from among titanium, zirconium, tantalum, niobium, silicon, chromium, tungsten and molybdenum and a metallic phase comprising an alloy or intermetallic compound filled in the gaps within or among the skeletal structures, or (2) a sintered composite material comprising superabrasive grains dispersed in the surface or surface layer part including the part corresponding to the working face of a matrix or the whole of a matrix containing a metallic substance produced by combustion synthesis and/or a refractory. It is effective to use also superabrasive grains coated with a metal or nonmetal in a specified manner.
