Abstract: A method for manufacturing a fuel contacting component that facilitates reducing coke formation on at least one surface of the fuel contacting component is disclosed herein. The method includes applying a slurry composition including a powder including aluminum to the component surface, wherein the fuel contacting component is formed by an additive manufacturing process. The slurry composition is heat treated to diffuse the aluminum into the component surface. The heat treatment comprises forming a diffusion aluminide coating on the component surface, wherein the diffusion coating comprises a diffusion sublayer formed on the component surface and an additive sublayer formed on the diffusion sublayer. The method further comprises removing the additive sublayer of the diffusion aluminide coating with at least one aqueous solution such that the diffusion sublayer and the component surface are substantially unaffected, wherein the diffusion layer facilitates preventing coke formation on component surface.
