High thermal conductivity hardfacing

摘要

A hardmetal composition comprises tungsten carbide in an amount greater than 50 weight percent of the hardmetal composition. In addition, the hardmetal composition comprises a binder material consisting of at least 90 weight percent nickel, a binder flux between 3.5 to 10.0 weight percent chosen from the group consisting of boron and silicon, and less than 1.0 weight percent other components.
