Abstract: A method includes applying a material coating to a surface of a machine component, wherein the material coating is formed from a combination of a hardfacing material, aluminum-containing particles, and a braze material. The method also includes thermally treating the material coating at a temperature to generate an oxide layer comprising aluminum from the aluminum-containing particles, wherein the oxide layer is configured to reduce oxidation of the hardfacing material, and the braze material is configured to facilitate binding between the material coating and the surface of the machine component.

Abstract: A method of manufacturing a target component is disclosed. The method includes inputting, into a binder jetting additive manufacturing system, instructions for manufacturing a desired target component, wherein the target component includes at least one internal channel defined at least by a circuitous path including at least one bend; printing the target component via a binder jet additive manufacturing process to form a green body target component, wherein during the printing at least one port is formed that extends from an external surface of the target component to the at least one internal channel; and depowdering the at least one internal channel by accessing the at least one port formed on the green body target component.
