What is a cermet?

A cermet is a composite material composed of ceramic and metallic components, designed to combine the desirable properties of both materials. Typically, cermets exhibit high hardness and wear resistance from the ceramic phase, while the metallic phase provides toughness and ductility. They are commonly used in applications such as cutting tools, wear-resistant surfaces, and high-temperature environments. The specific properties of a cermet can be tailored by adjusting the ratio of ceramic to metal and the types of materials used.
