Abstract: 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.

Abstract: A multilayer protective coating system includes a turbine engine component substrate formed of a ceramic matrix composite material, an environmental barrier coating layer including a rare earth disilicate material deposited directly on the substrate, and a plurality of pairs of alternating layers of the rare earth disilicate material and a rare earth monosilicate material deposited and sintered directly on the environmental barrier coating layer. Each layer of the plurality of pairs of alternating layers is relative less thick as compared with the environmental barrier coating layer.

IPC: F03G7/06
Abstract: 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.

Abstract: Methods and systems are provided for filling cracks in an environmental barrier coating and/or a thermal barrier coating (EBC/TBC). The method comprises locating a component within an enclosure of an apparatus, the component including a substrate having the EBC/TBC thereon, wherein the EBC/TBC includes cracks extending from an exterior surface of the EBC/TBC toward the substrate, reducing pressure within the enclosure to a first pressure that is less than atmospheric pressure, applying a filler slurry to the exterior surface to cover the cracks while the EBC/TBC is exposed to the first pressure, increasing the enclosure to a second pressure that is greater than the first pressure, wherein the second pressure is sufficient to cause the filler slurry on the EBC/TBC to infiltrate into and fill the cracks, and sintering the filler slurry sufficient to cure the filler slurry within the cracks.

Abstract: A method of applying a protective coating to a substrate includes the steps of: providing a turbine engine component substrate formed of a ceramic matrix composite material, forming an environmental barrier coating layer including a rare earth disilicate material directly on the substrate, treating an outer surface of the environmental barrier coating layer to form a thermal barrier coating layer including a porous rare earth monociliate material directly on the environmental barrier coating layer. The step of treating the outer surface is performed using a thermal process consisting of the application of heat or a chemical-thermal process consisting of the application of heat and a chemical. The method further includes infiltrating at least a portion of the pores with a metal solution or suspension.
