Abstract (en)

Methods are provided for producing components. The methods include applying a slurry or paste to a surface of a substrate, wherein the substrate includes a nickel-based superalloy, drying the slurry or paste applied to the surface to define a coated substrate, and performing a heat treatment on the coated substrate to simultaneously densify and/or crystallize the dried slurry or paste to thereby form a coating that is bonded to the surface and to age the substrate to achieve a specific hardness therein by controllably forming precipitates of an intermetallic phase within the substrate and/or controllably modifying a size distribution of the precipitates of the intermetallic phase within the substrate, wherein residual stress within the substrate are preserved during the heat treatment.
