Abstract: Embodiments of the present disclosure generally relate to nanocomposite pellicles for extreme ultraviolet lithography systems. A pellicle comprises a plurality of carbon nanotubes arranged in a planar sheet formed from a plurality of metal catalyst droplets. The plurality of carbon nanotubes are coated in a first conformal layer of boron nitride. The pellicle may comprise a plurality of boron nitride nanotubes formed simultaneously as the first conformal layer of boron nitride. The pellicle may comprise a carbon nanotube coating disposed on the first conformal layer of boron nitride and a second conformal layer of boron nitride or boron nitride nanotubes disposed on the carbon nanotube coating. The pellicle is UV transparent and is non-reactive in hydrogen radical environments.

Abstract: A gas distribution assembly for applying a coating on an interior of a plurality of components includes a support with a plurality of component cavities formed within the support. Each component cavity corresponds to a respective component to fluidly couple with an interior of the respective component. A first gas source flow line is fluidly coupled with each of the component cavities to provide a first gas from a first gas source to each of the component cavities, and a second gas source flow line is fluidly coupled with each of the component cavities to provide a second gas from a second gas source to each of the component cavities.

Abstract: Embodiments of the present disclosure generally relate to protective coatings on an aerospace component and methods for depositing the protective coatings. In one or more embodiments, a method for depositing a coating on an aerospace component includes depositing one or more layers on a surface of the aerospace component using an atomic layer deposition or chemical vapor deposition process, and performing a partial oxidation and annealing process to convert the one or more layers to a coalesced layer having a preferred phase crystalline assembly. During oxidation cycles, an aluminum depleted region is formed at the surface of the aerospace component, and an aluminum oxide region is formed between the aluminum depleted region and the coalesced layer. The coalesced layer forms a protective coating, which decreases the rate of aluminum depletion from the aerospace component and the rate of new aluminum oxide scale formation.

Abstract: Embodiments of the present disclosure generally relate to protective coatings on an aerospace component and methods for depositing the protective coatings. In one or more embodiments, a method for depositing a coating on an aerospace component includes exposing an aerospace component to a first precursor and a first reactant to form a first deposited layer on a surface of the aerospace component by a chemical vapor deposition (CVD) process or a first atomic layer deposition (ALD) process and exposing the aerospace component to a second precursor and a second reactant to form a second deposited layer on the first deposited layer by a second ALD process, where the first deposited layer and the second deposited layer have different compositions from each other.

Abstract: Embodiments of the present disclosure generally relate to protective coatings on substrates and methods for depositing the protective coatings. In one or more embodiments, a method of forming a protective coating on a substrate includes depositing a chromium oxide layer containing amorphous chromium oxide on a surface of the substrate during a first vapor deposition process and heating the substrate containing the chromium oxide layer comprising the amorphous chromium oxide to convert at least a portion of the amorphous chromium oxide to crystalline chromium oxide during a first annealing process. The method also includes depositing an aluminum oxide layer containing amorphous aluminum oxide on the chromium oxide layer during a second vapor deposition process and heating the substrate containing the aluminum oxide layer disposed on the chromium oxide layer to convert at least a portion of the amorphous aluminum oxide to crystalline aluminum oxide during a second annealing process.

Abstract: Methods for forming protective coatings on aerospace components are provided. In one or more embodiments, the method includes exposing an aerospace component to a first precursor and a first reactant to form a first deposited layer on a surface of the aerospace component by a first deposition process (e.g., CVD or ALD), and exposing the aerospace component to a second precursor and a second reactant to form a second deposited layer on the first deposited layer by a second deposition process. The first deposited layer and the second deposited layer have different compositions from each other. The method also includes repeating the first deposition process and the second deposition process to form a nanolaminate film stack having from 2 pairs to about 1,000 pairs of the first deposited layer and the second deposited layer consecutively deposited on each other.

Abstract: Using the systems and methods discussed herein, CMAS corrosion is inhibited via CMAS interception in an engine environment and/or is prevented or reduced by the formation of a metal oxide protective coating on a hot engine section component. The CMAS interception can occur while the engine is in operation in flight or in a testing or quality control environment. The metal oxide protective coating can be applied over other coatings, including Gd-zirconates (GZO) or yttria-stabilized zirconia (YSZ). The metal oxide protective coating is applied at original equipment manufacturers (OEM) and can also be applied in-situ using a gas injection system during engine use in-flight or during maintenance or quality testing. The metal oxide protective coating contains a rare earth element, aluminum, zirconium, chromium, or combinations thereof.

The metal oxide template layer contains chromium oxide, chromium oxide hydroxide, or a combination thereof. The aluminum oxide layer contains α-Al2O3. The metal oxide template layer and the aluminum oxide layer have a corundum crystal structure and have crystal structures with a lattice mismatch of about 0.1% to about 10%.
