A high-temperature long lifespan electrode includes a through type aluminum sheet, a plurality of first hollow protrusion members protruded to one side of the through type aluminum sheet, a plurality of second hollow protrusion members protruded to the other side of the through type aluminum sheet, a metal protection layer coated on the through type aluminum sheet, the plurality of first hollow protrusion members, a first active material sheet bonded to one surface of the through type aluminum sheet, and a second active material sheet bonded to the other surface of the second surface of the through type aluminum sheet.

To manufacture a chamber component for a processing chamber a first anodization layer is formed on a metallic article with impurities, the first anodization layer having a thickness greater than about 100 nm, and an aluminum coating is formed on the first anodization layer, the aluminum coating being substantially free from impurities. A second anodization layer can be formed on the aluminum coating.

A method of forming a bi-metallic casting. The method includes providing a metal preform of a desired base shape defining a substrate surface and removing a natural oxide layer and surface contamination from the substrate surface to yield a cleaned metal preform. The method further includes galvanizing the cleaned metal preform, yielding a galvanized metal preform followed by electroplating a thin nickel film on at least a portion of the substrate surface of the galvanized metal preform. Additionally, the method includes metallurgically bonding the portion of the metal preform having the nickel film with an overcast metal to form a bi-metallic casting. The nickel film promotes a metallurgical bond between the metal preform and the overcast metal.

A method for processing frameless shell materials, relating to the technical field of mobile terminal device shell processing, is provided and includes the following steps: S1 cutting a sheet material, S2 stamping and curling, S3 CNC processing, S4 grinding and cleaning, S5 surface T processing, and S6. nano-injection molding. The present disclosure adopts a stamping method and replaces traditional metal block CNC processing, which can reduce production costs. During the stamping process, the aluminum sheet is edge-curled and thickened to enhance the strength of the shell material. By cutting a step-shaped groove for screen installation, a frameless design is achieved, thereby reducing production costs and assembly procedures. The anodizing of the U-shaped frame surface allows the plastic to fully penetrate the aluminum shell surface, thereby enhancing integration and preventing plastic parts from falling off the U-shaped frame.

Disclosed herein is an aluminum oxide film remover for removing an oxide film on the surface of aluminum or aluminum alloy, which comprises silver ions and/or copper ions, a solubilizing agent for silver ions and/or copper ions, and a quaternary ammonium hydroxide compound, and has a pH value of 10 to 13.5. A method for surface treatment of aluminum or aluminum alloy is also disclosed, which comprises immersing a workpiece having aluminum or aluminum alloy at least on the surface thereof in the aluminum oxide film remover, and depositing the silver and/or copper contained in the remover on the surface of aluminum or aluminum alloy while removing the aluminum oxide film.

A thermally stable component formed of a tempered aluminum alloy casting which reduced costs is provided. The aluminum alloy typically has an elongation of at least 8% after casting, which is preferred for self-piercing rivet processes. The aluminum alloy leaves a casting facility in the as-cast (F temper) condition. The cast aluminum alloy is then shipped to another entity, such as an OEM, and is subjected to an artificial aging process, such as on the OEM's existing paint line, rather than at the casting facility. The artificial aging process typically includes electrodeposition coating and curing. The components that can be formed by the reduced cost method include lightweight automotive vehicle components, including structural, body-in-white, suspension, or chassis components, such as front shock towers, front body hinge pillars, tunnels, and rear rails.
