Abstract

The disclosed invention describes a method for cladding surfaces of an earth boring apparatus, or the like, with a hardfacing material having an entrained, or encapsulated, heavy metal refractory carbide. The method includes heating the surface to the incipient melting temperature and applying a molten super-alloy matrix material that has a melting temperature below the melting temperature of the carbide. The super-alloy, in a powder form, is pre-mixed with the carbide material, also in a powder form, such that, when the molten surface and the molten super-alloy cool, they form a metallurgical bond, at the surface, with the carbide material mechanically retained within the solidified matrix material.
