A method for preparing a metal-based part, the method comprising applying a slurry to a surface of a temporary substrate to thereby form a slurry-coated temporary substrate, wherein the slurry comprises a Co-, Ni-, or Fe-based metal-based material, a binder, and a solvent; drying the slurry-coated temporary substrate to remove the solvent and to thereby form a coating layer having green strength; heating the coating layer to remove the binder; heating the coating layer to sinter the metal-based material into a continuous metal alloy layer; and separating the substrate from the coating layer. A powder metallurgy preform comprising a powder metallurgy green coating on a preform substrate.
