    摘要： Dispersion strengthened aluminum base alloys are shaped into metal parts by high strain rate forging compacts or extruded billets composed thereof. The number of process steps required to produce the forged part are decreased and strength and toughness of the parts are increased. The dispersion strengthened alloy may have the formula Albal,Fea,SibXc, wherein X is at least one element selected from Mn, V, Cr, Mo, W, Nb, and Ta, “a” ranges from 2.0 to 7.5 weight-%, “b” ranges from 0.5 to 3.0 weight-%, “c” ranges from 0.05 to 3.5 weight-%, and the balance is aluminum plus incidental impurities. Alternatively, the dispersion strengthened alloy may be described by the formula Albal,Fea,SibVdXc, wherein X is at least one element selected from Mn, Mo, W, Cr, Ta, Zr, Ce, Er, Sc, Nd, Yb, and Y, “a” ranges from 2.0 to 7.5 weight-%, “b” ranges from 0.5 to 3.0 weight-%, “d” ranges from 0.05 to 3.5 weight-%, “c” ranges from 0.02 to 1.50 weight-%, and the balance is aluminum plus incidental impurities. In both cases, the ratio [Fe+X]:Si in the dispersion strengthened alloys is within the range of from about 2:1 to about 5:1.

    摘要： Methods and apparatus to make multilayer thermal barrier coatings for superalloy substrates such as turbine blades or vanes are disclosed. The methods produce non-homogeneous, nanometer-size, successive layers and a non-homogeneous interfacial layer without the use of baffles. Methods are also disclosed to use a lower cost metallic source and an oxygen bleed to create alumina or tantalum oxide vapor, to use a tantalum oxide or an alumina ingot and a low pressure inert gas feed to direct the vapor clouds, to use pulsed evaporation from a secondary vapor source to create non-homogeneous multilayer coating on non-rotated substrates, to use an electric bias to direct the vapor clouds, and to use a mechanical system to direct the vapor clouds or move and position the article to be coated in the clouds.

    摘要： A turbine engine component includes an electron beam-physical vapor deposition thermal barrier coating covering at least a portion of a substrate. The thermal barrier coating includes an inner layer having a columnar-grained microstructure with inter-columnar gap porosity. The inner layer includes a stabilized ceramic material. The thermal barrier coating also includes a substantially non-porous outer layer, covering the inner layer and including the stabilized ceramic material. The outer layer is deposited with continuous line-of-sight exposure to the vapor source under oxygen deficient conditions. The outer layer may further comprise a dopant oxide that is more readily reducible than the stabilized ceramic material. During deposition, the outer layer may also have an oxygen deficient stoichiometry with respect to the inner layer. Oxygen stoichiometry in the outer layer may be restored by exposure of the coated component to an oxidizing environment.

    摘要： A durable protective coating may be formed by applying a thin layer of metastable alumina to a bond coating on a substrate. A thermal barrier coating may then be applied to the metastable alumina and the resulting part may be heat treated to transform the metastable alumina to a mixed alpha alumina having particles of the thermal barrier coating, such as zirconia in the case of an yttria stabilized zirconia thermal barrier coating, dispersed therein. The resulting thermal barrier coating may inhibit microbuckling of the thermally grown oxide scale that grows over time at the thermal barrier coating-bond coating interface.

    摘要： A plurality of powders is admixed to form a substantially homogenous powder mixture comprising each of the alloy elements. At least one of the powders consists essentially of a substantially pure elemental metal. The substantially homogenous powder mixture is cold gas-dynamic sprayed on the substrate to form a coating of the alloy elements. The coating is then heated until the alloy elements inter-diffuse and form the alloy. In an exemplary embodiment, the substantially homogenous powder mixture includes stoichiometric amounts of each of the alloy elements, and each of the powders consists essentially of a substantially pure form of one of the alloy elements.

    摘要： A method is provided for forming a graded coating on a surface of a substrate. The method comprises the step of cold gas-dynamic spraying powder mixtures on the substrate surface to form the graded coating thereon. The method does not distort the substrate and does not require the use of an apparatus that needs to be stopped and re-started each time the composition of the graded coating changes. Moreover, the method is generally inexpensive, efficient, and yields high quality graded coatings.

    摘要： In a method for coating a surface of a turbine component with an environment-resistant aluminide, a coating is formed by cold gas-dynamic spraying a powder material on the turbine component surface, the powder material comprising aluminum, platinum, and at least one additional metal selected from the group consisting of nickel, chromium, hafnium, silicon, yttrium, rhenium, zirconium, cobalt, and tantalum. After forming the coating, at least one thermal diffusion treatment is performed on the turbine component to metallurgically homogenize the coating and thereby form an aluminide coating that includes by weight about 12 to about 30% aluminum, up to about 50% platinum, about 2 to about 25% chromium, about 1 to about 5% hafnium, about 1 to about 5% silicon, about 0.1 to about 1% yttrium, and about 1 to about 3% Zr, and nickel.
