摘要： Systems for masking and sealing a component for surface treatment. A system includes a pair of fixture plates disposed on opposite ends of the component from each other. One or more inner sleeves are inserted into the component to mask and seal at least a portion of the component. An outer sleeve extends between the fixture plates to seal outside of the component. A pair of fixture rods extend between the first and second fixture plates and couple the first and second fixture plates together. The system is configured to effect surface treatment of an exposed area of the component, at least a portion of the exposed area defined by and disposed adjacent to the one or more inner sleeves.

摘要： This disclosure provides a method of pressure sintering an environmental barrier coating on a surface of a ceramic substrate to form an article. The method includes the steps of etching the surface of the ceramic substrate to texture the surface, disposing an environmental barrier coating on the etched surface of the ceramic substrate wherein the environmental barrier coating includes a rare earth silicate, and pressure sintering the environmental barrier coating on the etched surface of the ceramic substrate in an inert or nitrogen atmosphere at a pressure of greater than atmospheric pressure such that at least a portion of the environmental barrier coating is disposed in the texture of the surface of the ceramic substrate thereby forming the article.

摘要： Methods are disclosed for fabricating heat exchangers and Heat Exchanger (HX) tubes, as are heat exchangers fabricated in accordance with such methods. In embodiments, the method includes fabricating an HX tube by at least partially forming the elongated tube body utilizing a cold spray process during which a metallic feedstock powder is deposited over a removable mandrel. The HX tube is separated from the removable mandrel at some juncture following cold spray deposition of the tube body.

摘要： Ionic liquid bath plating methods for depositing aluminum-containing layers utilizing shaped consumable aluminum anodes are provided, as are turbomachine components having three dimensionally-tailored, aluminum-containing coatings produced from such aluminum-containing layers. In one embodiment, the ionic liquid bath plating method includes the step or process of obtaining a consumable aluminum anode including a workpiece-facing anode surface substantially conforming with the geometry of the non-planar workpiece surface. The workpiece-facing anode surface and the non-planar workpiece surface are positioned in an adjacent, non-contacting relationship, while the workpiece and the consumable aluminum anode are submerged in an ionic liquid aluminum plating bath. An electrical potential is then applied across the consumable aluminum anode and the workpiece to deposit an aluminum-containing layer onto the non-planar workpiece surface. In certain implementations, additional steps are then performed to convert or incorporate the aluminum-containing layer into a high temperature aluminum-containing coating, such as an aluminide coating.

摘要： Engine structures and methods of forming the engine structures are provided herein. In an embodiment, an engine structure includes a silicon-based ceramic-containing substrate having an in-tolerance surface and one or more barrier layers disposed on the in-tolerance surface of the ceramic-containing substrate. The ceramic-containing substrate includes a bulk zone and a gradient zone. The bulk zone includes a first bulk material. The gradient zone includes the first bulk material and a second material that is different from the first bulk material. The gradient zone has a gradient of increasing concentration of the second material from the bulk zone to the in-tolerance surface of the ceramic-containing substrate.

摘要： Embodiments of an electromagnetic coil assembly are provided, as are methods for the manufacture of an electromagnetic coil assembly. In one embodiment, the method includes joining a first end portion of a braided lead wire to a coiled magnet wire. A dielectric-containing material is applied in a wet-state over the coiled magnet wire and over the first end portion of the braided lead wire. The dielectric-containing material is cured to produce an electrically-insulative body in which the coiled magnet wire and the first end portion of the braided lead wire are at least partially embedded. Prior to application of the dielectric-containing material, the braided lead wire is at least partially impregnated with a masking material deterring wicking of the dielectric-containing material into an intermediate portion of the braided lead wire.

摘要： Embodiments of a method for producing powder mixtures having uniform dispersion of ceramic particles within larger superalloy particles are provided, as are embodiments of superalloy powder mixtures. In one embodiment, the method includes producing an initial powder mixture comprising ceramic particles mixed with superalloy mother particles having an average diameter larger than the average diameter of the ceramic particles. The initial powder mixture is formed into a consumable solid body. At least a portion of the consumable solid body is gradually melted, while the consumable solid body is rotated at a rate of speed sufficient to cast-off a uniformly dispersed powder mixture in which the ceramic particles are embedded within the superalloy mother particles.
