DIAMOND-CONTAINING CEMENTED METAL CARBIDE

Cemented tungsten carbide rock bit inserts (18) have diamond particle dispersed therein for enhanced hardness and war resistance. The cobalt matrix is primarily the face centered cubic crystal structure for enhanced ductility and toughness. Such inserts (18) are formed by introducing excess non-diam...
