Abstract
Carbide pellets including relatively small amounts of metallic binder are produced by steps of pressing, comminuting, shaping and sintering. The carbide pellets may be used as wear resistant hard facing materials that are applied to various types of tools. The carbide pellets provide improved mechanical properties such as hardness and abrasiveness while maintaining required levels of toughness and strength.
