Abstract: An article treatment method includes providing an article including a substrate composed of a substrate material having an undesirable substrate feature. The undesirable substrate feature may include a recess, and a portion of the substrate containing the undesirable substrate feature may be removed to form a recess in a surface of the substrate. A feedstock mixture including a filler material and a liquid carrier is introduced into an HVAF apparatus having a combustion gas stream with a temperature greater than the melting point of the filler material. The filler material is applied to the recess by expelling the filler material while maintained at a temperature less than the melting point of the filler material by the liquid carrier. The filler material and an area of the substrate bordering the recess are heat treated, forming a treated portion.

Abstract: Provided is a method of fabricating an article, including deforming an ingot of a nickel-based superalloy to form an intermediate article, forming a substantially homogeneous dispersion of Laves phase precipitates within the intermediate article, wherein the Laves phase precipitates are present at a concentration of at least about 0.05% by volume and the precipitates have a mean diameter of less than one micron. Also provided is a nickel-based superalloy including a substantially homogeneous dispersion of Laves phase precipitates, wherein the intergranular and transgranular Laves phase precipitates are present at a concentration of at least about 0.1% by volume and wherein the precipitates have a mean diameter of less than one micron. Precipitation of Laves phase may control microstructure during Thermo-mechanical processing and produce superalloys with refined grain size.

Abstract: Coatings for substrates, such as superalloy substrates, are provided. The coating can include: 15 wt % to 45 wt % cobalt; 20 wt % to 40 wt % chromium; 2 wt % to 15 wt % aluminum; 0.1 wt % to 1 wt % yttrium; and nickel. The coatings may include nickel, cobalt, chromium and aluminum, and other optional additives to improve oxidation and corrosion resistance of the substrate without significant debit to its mechanical properties.
