METAL/METAL BORIDE CERMETS

摘要

Self-supporting bodies are produced by reactive infiltration of a <> typically resulting in a composite comprising a parent metal boride and metal. The mass to be infiltrated may contain one or more inert fillers admixed with the boron source to produce a composite by reactive infiltration, which composite comprises a matrix of metal and parent metal boride embedding the filler. The relative amounts of reactants and process conditions may be altered or controlled to yield a body containing varying volume percents of ceramic, metal and/or porosity.
