Abstract: 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.

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.

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.
