    摘要: A thermal management article is disclosed including a substrate and a first coating disposed on the substrate. The first coating includes a first coating surface and at least one passageway disposed between the substrate and the first coating surface. The at least one passageway defines at least one fluid pathway. A method for forming a thermal management article is disclosed including attaching at least one passageway to a substrate. The at least one passageway includes a passageway wall having a wall thickness and defines at least one fluid pathway. A first coating is applied to the substrate and the passageway wall, forming a first coating surface. The at least one passageway is disposed between the substrate and the first coating surface.

    摘要: An article and a method for forming a single crystal casting are disclosed. The article includes a single crystal nickel-based superalloy having a composition including greater than about 80 ppm boron (B) and a substantially single crystal microstructure with at least one grain boundary. A creep rupture strength of the article is substantially maintained up to a mismatched grain boundary of about 40 degrees. The method for forming a single crystal casting includes positioning a mold on a cooling plate, the mold including a single crystal selector, providing a molten nickel-based superalloy composition in the mold, the molten composition including greater than about 80 ppm boron (B), cooling the molten composition with the cooling plate, and forming a unidirectional temperature gradient by withdrawing the mold from within a heat source to form the single crystal casting including a substantially single crystal microstructure having at least one grain boundary.

    摘要: A cast nickel-base superalloy that includes iron added substitutionally for nickel. The cast nickel base superalloy comprises, in weight percent about 1-6% iron, about 7.5-19.1% cobalt, about 7-22.5% chromium, about 1.2-6.2% aluminum, optionally up to about 5% titanium, optionally up to about 6.5% tantalum, optionally up to about 1% Nb, about 2-6% W, optionally up to about 3% Re, optionally up to about 4% Mo, about 0.05-0.18% C, optionally up to about 0.15% Hf, about 0.004-0.015 B, optionally up to about 0.1% Zr, and the balance Ni and incidental impurities. The superalloy is characterized by a □′ solvus temperature that is within 5% of the □′ solvus temperature of the superalloy that does not include 1-6% Fe and a mole fraction of □′ that is within 15% of the mole fraction of the superalloy that does not include 1-6% Fe.

    摘要: A process of forming a calcium-magnesium-aluminosilicate (CMAS) penetration resistant coating, and a CMAS penetration resistant coating are disclosed. The process includes providing a thermal barrier coating having a dopant, and exposing the thermal barrier coating to calcium-magnesium-aluminosilicate and gas turbine operating conditions. The exposing forming a calcium-magnesium-aluminosilicate penetration resistant layer. The coating includes a thermal barrier coating composition comprising a dopant selected from the group consisting of rare earth elements, non-rare earth element solutes, and combinations thereof. Additional or alternatively, the coating includes a thermal barrier coating and an impermeable barrier layer or a washable sacrificial layer positioned on an outer surface of the thermal barrier coating.
