This invention provides a composite product and an effective method for producing the same, based on an SHS or intense heat producing process. Said composite essentially comprises either (1) one or more skeletal structures of three dimensionally joined pieces of at least one ceramic material selected from carbide, boride, nitride and silicide of titanium, zirconium, tantalum, niobium, silicon, chromium, tungsten, and molybdenum, and metallic material of alloy and/or intermetallic compound which fills the gaps within each and between adjacent skeletal structures, or (2) a matrix consisting of SHS products of metallic and/or ceramic substances, and particles of superabrasive selected from diamond and high pressure polymorphism of boron nitride, which are held and distributed in the matrix in the whole, in the surface or surface area comprising the portion corresponding to the end working face. Also effective is the use of superabrasive particles coated with metallic and/or non-metallic materials by some specific techniques.

Composite and method for producing the same

Sintered composites containing superabrasive particles

The invention provides a superabrasive containing composite product, comprising and/or prepared on the intense heating of an SHS process, self-propagating high-temperature synthesis. An effective method of such product is also provided. Said composite comprises a substrate of shaped metallic block and a functional layer of ceramic materials containing superabrasive particles, which is joined on a surface of the former, by means of and intermediated by molten metal which occurred during the SHS process.
