Abstract: The present disclosure provides a cleaning system, including a first sub-chamber, a second sub-chamber adjacent to the first sub-chamber, and a third sub-chamber adjacent to the second sub-chamber. A first divider is positioned between the first and the second sub-chambers. A second divider is positioned between the second and the third sub-chambers. A vacuum system is coupled to the third sub-chamber to generate a vacuum pressure in the third sub-chamber that is less than a pressure of the first sub-chamber to create a pressure differential to induce a pressurized flow of a first cleaning media from the first sub-chamber to the third sub-chamber through an internal passage of a component positioned in the second sub-chamber. A filtering system is coupled to the first sub-chamber and the third sub-chamber to remove and filter the first cleaning media from the third sub-chamber and return the first cleaning media to the first sub-chamber.

Abstract: An additive manufacturing powder particle including a surface and at least one functional group formed on the surface, wherein the at least one functional group increases laser energy absorption of the additive manufacturing powder particle. The additive manufacturing particle is treated with plasma radiation to form hydroxyl functional groups on a surface of the additive manufacturing powder particle, where the hydroxyl functional groups have a molecular vibrational frequency corresponding to a laser wavenumber range of laser energy of an additive manufacturing process, and where the plasma radiation treating the additive manufacturing powder particles depends on the laser energy of the additive manufacturing process. Treating the additive manufacturing powder particle with the plasma radiation increases laser energy absorption of the additive manufacturing powder particle when the additive manufacturing particle is exposed to the laser energy, produced by a carbon dioxide laser, of the additive manufacturing process.

Abstract: The present disclosure provides electrolyte solutions for electrodeposition of zinc-manganese alloys, methods of forming electrolyte solutions, methods of electrodepositing zinc-manganese alloys, and multilayered zinc-manganese alloys. An electrolyte solution for electroplating can include a metal salt, boric acid, an alkali metal chloride, polyethylene glycol, and a hydroxy benzaldehyde. An electrolyte solution can be formed by dissolving a metal salt, boric acid, an alkali metal chloride, polyethylene glycol, and a hydroxy benzaldehyde in water or an aqueous solution. Electrodepositing zinc-manganese alloys on a substrate can include introducing a cathode and an anode into an electrolyte solution comprising a metal salt, boric acid, an alkali metal chloride, polyethylene glycol, and a hydroxy benzaldehyde. Electrodepositing can further include passing a current between the cathode and the anode through the electrolyte solution to deposit zinc and manganese onto the cathode.

Abstract: Curable compositions are provided. In embodiments, a curable composition comprises curable prepolymers selected from the group consisting of epoxy prepolymers and silicone prepolymers, and a curing rate modifier that increases a rate of crosslinking reactions between the curable prepolymers as compared to a comparative curable composition without the curing rate modifier, wherein the curing rate modifier does not cure the curable composition in the absence of a hardener present in the curable composition, a catalyst present in the curable composition, water, or a combination thereof. Methods of using the curable compositions are also provided.

Abstract: A sound attenuation panel that includes an incident wall and a frame unit connected to the incident wall. The incident wall defines an aperture therethrough. The frame unit includes multiple spoke members spaced apart from one another and radially extending from one or more central hub openings of the frame unit. The one or more central hub openings align with the aperture of the incident wall. The frame unit defines channels between adjacent pairs of the spoke members. The channels fluidly connect to the one or more central hub openings. The frame unit is configured to receive sound waves into the central hub opening through the aperture of the incident wall to dissipate the sound waves through the channels between the spoke members.

Abstract: A corrosion-resistant coating on an aluminum-containing substrate such as an aluminum substrate, an aluminum alloy substrate (e.g., AA 2024, AA 6061, or AA7075), or other aluminum-containing substrate includes a corrosion inhibitor-incorporated Zn—Al layered double hydroxide (LDH) layer and a sol-gel layer. A zinc salt and a corrosion inhibitor (e.g., a salt of an oxyanion of a transition metal such as a vanadate) is dissolved to form a zinc-corrosion inhibitor solution, and the substrate is immersed in or otherwise contacted with the solution to form the corrosion inhibitor-incorporated Zn—Al LDH layer on the substrate. A sol-gel composition is applied on the corrosion inhibitor-incorporated Zn—Al LDH layer of the substrate to form a sol-gel layer, and the sol-gel layer is cured.
