Abstract:Cemented carbides are composite materials used in a wide variety of applications requiring the right combination of mechanical strength and wear resistance under harsh environments (i.e. metal cutting and shaping, civil engineering, mining, valves for the chemical industry, etc). The most common compositions comprise tungsten carbide grains bonded with a cobalt based metallic matrix. The reason is twofold. On the one hand, WC-Co materials are relatively easy to sinter to full density state with the adequate pr… Show more
