Abstract: A method for manufacturing an electromagnetic coil with an intentionally engineered heat flow path is provided. The method includes defining at least one preferential heat flow path for heat to flow from the electromagnetic coil. A plurality of different materials are selected, each having different heat flow properties. A determination is made as to which portions of the electromagnetic coil should be coated with each of the different materials that will result in the at least one preferential heat flow path. The determined portions of the electromagnetic coil are then coated with each of the different materials to make a coated electromagnetic coil, and the coated electromagnetic coil is encased in a coil cartridge.

Abstract: Disclosed is a superalloy gas turbine engine component including a glass coating. The glass coating is configured for resistance to hot corrosion caused by molten salts of sodium, magnesium, vanadium, and/or sulfur dioxide. The glass coating includes a mixture of two or more metal oxides, which are preferably selected from: barium oxide, silicon oxide, strontium oxide, aluminum oxide, magnesium oxide, calcium oxide, cobalt oxide, boron oxide, iron oxide, zirconium oxide, nickel oxide, and titanium oxide. The glass coating is in fully crystalline form and/or a mixture of crystalline and glass phases, and it has a coefficient of thermal expansion of from about 10 to about 18 μm/m-° C. The glass coating has a thickness over the superalloy gas turbine engine component of about 0.5 mils to about 10 mils.

Abstract: Systems and methods for additive manufacturing support removal of an additive manufactured component are provided. The method includes additively manufacturing a built component including at least one support having a thickness, and gaseous carburizing the built component and the at least one support to form a carburized component and at least one carburized support. Each of the carburized component and the at least one carburized support have a carburization layer with a predefined depth. The method includes removing the carburization layer to form the component devoid of the at least one carburized support.

Abstract: 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 the steps or processes of obtaining a Non-Equilibrium Alloy (NEA) feedstock powder comprised of an alloy matrix throughout which at least one minority constituent is dispersed. The first minority constituent precipitates from the alloy matrix when the NEA feedstock powder is exposed to temperatures exceeding a critical temperature threshold (TCRITICAL) for a predetermined time period. A cold spray process is carried-out to at least partially form the HX tubes from the NEA feedstock powder; and the HX tubes are subsequently installed in the heat exchanger. The HX tubes are exposed to a maximum temperature (TSPRAY_MAX) during the cold spray process, which is maintained below TCRITICAL to substantially preserve the non-equilibrium state of the NEA feedstock powder through cold spray deposition.
