Introduction of Ti(C,N)-based Cermet
1.Definition: 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).
2.Application area
The unique physical and chemical properties of Ti(C, N)-based cermets makes it a promising material for cutting tools, 3C molds, high temperature wear-resistant parts and special cutting blades for cables and chemical fibers, etc.
