Cermet

Ti(C, N)-based cermet is a kind of composite material consisting of ceramic particles bonded with a metal binder phase, which combines the favorable properties of ceramics (high hardness and wear, corrosion and high-temperature oxidation resistance) with those of metals (toughness especially).
