摘要： An improved hardfacing composition and method are shown for use in manufacturing an earth boring bit. The hardfacing composition is formed by combining titanium carbide with a hard-metal alloy of the iron or cobalt family. The hardfacing composition is then applied to the friction bearing surface of the rock bit.
