摘要： A coating and method for overcoating a TBC on a component used in a high-temperature environment, such as the combustor section of an industrial gas turbine. The coating defines the outermost surface of the component and is formed of at least two layers having different compositions. An inner layer of the coating contains alumina in a first silica-containing matrix material that is free of zinc titanate. An outer layer of the coating contains alumina, a glass material, and zinc titanate in a second silica-containing matrix material. The outer layer of the coating has a surface roughness of not greater than three micrometers Ra and forms the outermost surface of the component. The coating reduces the component temperature by reducing the convective and radiant heat transfer thereto.

摘要： A coating system and method for reducing the tendency for hydrocarbon fluids, such as fuels and oils, to form carbonaceous deposits that adhere to a wall of a containment article. Of particular concern are carbonaceous deposits that form at temperatures below about 650° F. (about 345° C.). The coating system combines an outermost layer of platinum with a ceramic barrier layer. The coating system significantly reduces the formation of carbonaceous deposits and the adhesion of such deposits. To further reduce wall and hydrocarbon fluid temperatures and formation of carbonaceous deposits, the coating system is preferably applied to the surface of the wall wetted by the fluid, as well as the opposite surface of the wall exposed to a surrounding environment. The outermost layers serve as radiation shields to reduce heat transfer from the surrounding environment to the wall, and from the wall to the hydrocarbon fluid.

摘要： A thermal barrier coating for an underlying metal substrate of articles that operate at, or are exposed to, high temperatures, as well as being exposed to environmental contaminant compositions. This coating includes an inner layer nearest to the underlying metal substrate comprising a ceramic thermal barrier coating material, as well as an outer layer having an exposed surface and comprising tantalum oxide in an amount sufficient to protect the thermal barrier coating at least partially against environmental contaminants that become deposited on the exposed surface and optionally an intermediate layer between the inner and outer layers comprising alumina. This coating can be used to provide a thermally protected article having a metal substrate and optionally a bond coat layer adjacent to and overlaying the metal substrate. The thermal barrier coating can be prepared by forming the inner layer comprising the ceramic thermal barrier material, optionally forming the intermediate layer comprising the alumina over the inner layer, and then forming the outer layer comprising the tantalum oxide over the intermediate (inner) layer.

摘要： A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a paste-like mixture of a ceramic composition comprising ceramic powders and nano-sized ceramic materials in a binder, further including an accelerant, is applied to the surface area of the component, and is optionally smoothed using mechanical means. The composition is then allowed to dry and cure to form a dried coating having polymeric characteristics. Upon subsequent heating, the dried coating reacts to produce a glassy ceramic repair coating. Due to the thixotropic properties of the coating composition upon application to a component, the repair method can be performed in-situ while the component remains installed in its operating environment.

摘要： A process of forming a ceramic coating on a component. The process generally entails placing the component in a coating chamber containing oxygen and an inert gas, heating a surface of the component to a temperature of about 100 to about 150° C., and then generating a metal vapor from at least one metal target using a microwave-stimulated, oxygen-containing sputtering technique. The metal vapor is then caused to condense on the component surface to form a metal layer, after which the metal layer is treated with a microwave-stimulated plasma to oxidize the metal layer and form an oxide layer having a columnar microstructure. The generating, condensing and treating steps can be repeated any number of times to form multiple oxide layers that together constitute the ceramic coating.

摘要： An anti-stick coating that inhibits the adhesion of contaminants that form deposits on the internal cooling passages of gas turbine engine components. The anti-stick coating is formed as an outer coating of the internal cooling passages, and preferably overlies an environmental coating such as a diffusion aluminide coating formed on the passage surfaces. The outer coating has a thickness of not greater than three micrometers, and is resistant to adhesion by dirt contaminants as a result of comprising at least one layer of tantala, titania, hafnia, niobium oxide, yttria, silica and/or alumina. The outer coating is preferably deposited directly on the environmental coating by chemical vapor deposition.

摘要： Methods are provided for producing large volumes of small antenna arrays. In one embodiment, the method comprises the steps of creating an antenna array pattern as a computer file, printing the created pattern onto the surface of a suitable transfer paper, placing the printed image surface in contact with the surface of a material to be etched, and transferring the printed image to the surface of the material to be etched. The transfer can be effected by any combination of chemicals, heat, and/or pressure. After transfer of the printed image, the transfer paper is removed. The step of removing the transfer paper optionally includes wetting the transfer paper in a manner that dissolves the transfer paper leaving the printed antenna pattern on the surface of the material to be etched. The method further includes the step of etching the non-printed portions of the material, preferably by chemical etching, and removing the printed pattern from the surface of the material to yield an antenna array comprising a non-etched portion of the substrate surface. Arrays, and substrates having an etch-resistant mask for making the arrays, are also provided.

摘要： A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a mixture of a ceramic composition comprising a ceramic powder in a binder is applied, preferably by spraying, to the surface area of the component. The binder is then allowed to dry to form a dried coating. Upon subsequent heating, the dried coating reacts to produce a ceramic-containing repair coating, wherein the coating comprises the ceramic powder in a matrix of a material formed when the binder was reacted. The binder is preferably a ceramic precursor material that can be converted immediately to a ceramic or allowed to thermally decompose over time to form a ceramic. The repair method can be performed while the component remains installed, e.g., in a gas turbine engine. The chemical composition is a liquid mixture that comprises ceramic material in at least two particle size ranges, as well as a nano-sized ceramic material and a binder that imparts thixotropic properties to the coating composition upon application to a component.
