摘要： A method for coating a surface of a metal component comprises the steps of cold gas-dynamic spraying a powder material on the metal component surface to form a coating, the powder material being sufficiently heated to impact the metal component surface at between about 30% and about 70% of the powder material's melting temperature in kelvins. Another method for coating a surface of a metal component using a powder material comprises the steps of heating the metal component surface to between about 30% and about 70% of the substrate's melting temperature, and then of the powder material's melting temperature in kelvins, and cold gas-dynamic spraying the powder material on the metal component surface to form a coating.

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： 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 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： The present invention provides a chromium and active elements modified platinum aluminide coating that may be used on a surface of a gas turbine engine component such as a turbine blade. The coating may be used as a protective coating that impedes the progress of corrosion, oxidation, and sulfidation in superalloy materials that comprise the substrate of the turbine blade. Additionally, the coating may be used as a bond coat onto which a thermal barrier coating is deposited. The presence of active elements as well as chromium and platinum provides improved corrosion, oxidation, and sulfidation resistance. The coating is applied using an electron beam physical vapor deposition. The coating is applied alternatively using selected sequential diffusion processing steps involving chromium, platinum and aluminum.

摘要： A method for repairing a titanium alloy surface of a turbine component includes the step of cold gas-dynamic spraying a powder material comprising at least one titanium alloy directly on the titanium alloy surface. The method may further include the steps of hot isostatic pressing the cold gas-dynamic sprayed turbine component, and performing a separate heat treating step after the hot isostatic pressing. Thus, the cold gas-dynamic spray process and post-spray processing can be employed to effectively repair degraded areas on compressor turbine components.
