    Abstract: A method of boriding a metal comprises forming a molten electrolyte comprising between about five weight percent and about fifty weight percent boron oxide, and contacting at least a portion of a metal with the molten electrolyte. Electrical current is applied to at least a portion of the metal while maintaining a temperature of the molten electrolyte below about 700° C. to diffuse boron atoms from the molten electrolyte into a surface of the at least a portion of the metal. A downhole tool including at least one borided component is also disclosed.

    Abstract: Methods of fabricating bodies of earth-boring tools include mechanically injecting a powder mixture into a mold cavity, pressurizing the powder mixture within the mold cavity to form a green body, and sintering the green body to a desired final density to form at least a portion of a body of an earth-boring tool. For example, a green bit body may be injection molded, and the green bit body may be sintered to form at least a portion of a bit body of an earth-boring rotary drill bit. Intermediate structures formed during fabrication of an earth-boring tool include green bodies having a plurality of hard particles, a plurality of matrix particles comprising a metal matrix material, and an organic material that includes a long chain fatty acid derivative. Structures formed using the methods of fabrication are also disclosed.

    Abstract: A multi-layer film for use in forming a layer of hardfacing on a surface of a tool includes a first layer and a second layer covering at least a portion of a surface of the first layer. The layers each include a polymer material and a plurality of particles dispersed throughout the polymer material. An intermediate structure includes a body of an earth-boring tool, a first material layer disposed over a surface of the body, and a second material layer disposed over the first material layer. A method of applying hardfacing includes providing a first material layer on a surface of a body of an earth-boring tool, providing a second material layer adjacent the first material layer, heating the body and removing the polymer material from the body of the earth-boring tool, and heating the body of the earth-boring tool to a higher temperature to form a layer of hardfacing material.
