Abstract
A method of making a flux-coated binder includes treating metal binder slugs to have an adherent surface, adding a flux powder to the treated metal binder slugs, and distributing the flux powder on the adherent surface of the metal binder slugs. A method of making a metal-matrix composite-based drill bit body includes loading a matrix powder into a bit body mold, loading a flux-coated binder into the mold on top of the matrix powder to form a load assembly, and heating the load assembly to allow the binder to infiltrate into the matrix powder.
