Method for producing a refractory composite material

Abstract

The present invention relates to producing refractory composite materials, practically poreless, and can be used for production of composite articles with increased size stability, wear resistance, high specific physico-mechanical properties and hardness, production of wear-resistant inserts in components and materials for tribo-technical purposes as well. The present method for producing a refractory composite material includes the steps of infiltration of a porous carbide work-piece by a metal resulting in preparation of an intermediate body, which is additionally treated in a melt of another metal at temperature exceeding the melting point of the metallic phase of the intermediate body, resulting in substitution of the metal in the intermediate body by the metal from the melt. The present invention extends the series of metals, which ban be introduced in composition of composite materials, and thus extends the application area of composite materials of this type.
