Systems and methods for a stabilized evaporable getter for increased handleability is provided. In certain embodiments, a method includes preparing a first getter material, a second getter material, and a metal material. Additionally, the method includes mixing the first getter material, the second getter material, and the metal material into a mixed getter material. Further, the method includes placing the mixed getter material into a getter holder. Also, the heat-treating the getter holder at a temperature below an activation temperature for an exothermic reaction of the mixed getter material but above a melting temperature of the metal material.

Stabilized evaporable getter for increased handleability

Systems and methods for oxide-based doping of an evaporable getter are described herein. In certain embodiments, a method includes mixing a first getter material with a second getter material to create a mixed getter material. The method also includes mixing an oxide dopant with the mixed getter material to create a doped getter material. Further, the method includes sealing the doped getter material within a device. Moreover, the method includes applying heat to the doped getter material to cause the doped getter material to emit a doped gas for deposition on internal surfaces of the device.

Oxide-based doping of evaporable getter

A method of making an electromagnetic coil for use in a high-temperature electromagnetic machine includes pre-coating magnet wire with a high-temperature insulation precursor to produce pre-coated magnet wire, winding, while applying in-situ a glass-ceramic slurry, the pre-coated magnet wire into a predetermined coil shape to produce a wet-wound green coil, and thermally processing the wet-wound green coil to produce a processed coil. In some instances, a second layer of a high-temperature insulation may be applied to the processed coil to produce a further insulated processed coil, and then thermally processing the further insulated processed coil to produce a further processed electromagnetic coil.

Method of assembling a high-temperature electromagnetic machine

In some examples, a method of making a filter includes heating a metal substrate to precipitate a first phase on a surface of the metal substrate from a metal alloy, the metal substrate defining a plurality of apertures configured to allow a gas to pass through the apertures. The metal substrate is the metal alloy including a first metal and a second metal. The method further includes growing a plurality of carbon nanotubes (CNTs) on the surface of the first metal of the first phase, and the CNTs are configured to capture at least one particle.

Filter media and system using the same

A method for using a shape memory alloy (SMA) with a non-evaporable getter (NEG) employed in a vacuum device is disclosed. The method comprises coupling a NEG component to a SMA component to form an NEG/SMA assembly pair; heating the NEG/SMA assembly pair to activate the NEG component; and packaging the activated NEG component with the SMA component to form an NEG/SMA package having a gas tight seal. The method further comprises installing the NEG/SMA package in the vacuum device; and heating the installed NEG/SMA package such that the SMA component is actuated to expose the activated NEG component to a vacuum chamber in the vacuum device.

Shape memory alloy enclosure for non-evaporable getters

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 &#x3bc;m/m-&#xb0; C. The glass coating has a thickness over the superalloy gas turbine engine component of about 0.5 mils to about 10 mils.
