摘要:
The invention relates to a method for producing a membrane and such membrane. The method comprises the steps of: —providing a container with electrolyte; —placing a structure in the container; and —providing at least two electrodes with a potential difference to achieve a plasma electrolytic oxidation on the structure. Preferably, the structure comprises a metallic structure, with the metallic structure chosen from the group of Titanium, Aluminum, Magnesium, Zirconium, Zinc and Niobium, and/or an alloy.

A cover (100) for an electronic device may include a metal plate (101) having a first metal region (110) formed of a metal; a through-hole (150) formed in a portion of the first metal region (110) of the metal plate (101); and an electrical open path (180) extending from the through-hole (150) to an end portion on one side of the first metal region (110) through metal oxidation. The cover of the electronic device can be used as an antenna and the oxidation process electrically separates the metal plate such that eddy currents are reduced and the antenna recognition distance is increased.
摘要:
A compressor wheel for a turbocharger comprising a central hub and a plurality of impeller blades extending outwardly from the hub. Each of the blades defines a leading edge, a trailing edge and a root portion which connects the blade to the hub. At least one of the blades has a surface provided with a variable thickness surface layer of a ceramic material. The leading edge of the blade is provided with a thicker surface layer of the ceramic material than the trailing edge and/or root portion of the blade.

A metal surface treated to have a distinct cosmetic appearance such as an integral layer that is glossy may be used in electronic devices. The surface treatment may include polishing a metal surface, texturing the polished metal surface, polishing the textured surface, followed by anodizing the surface, and then polishing the anodized surface. The metal surface may also be dyed to impart a rich color to the surface.

A process for repairing components (60) includes the steps of providing a component (60) having an affected area (44) on a surface (45) of a component (60) to be repaired; depositing a repair material over the affected area (44) on the surface (45) of the component (60) so that the repair material plastically deforms without melting and bonds to the affected area (44) upon impact with the affected area (44) and thereby covers the affected area (44); providing a sulfuric acid based anodizing solution; anodizing a deposited repair material on the surface (45) of said component (60) in the sulfuric acid based anodizing solution; consuming only a portion of the deposited repair material to form a hard anodized coating layer upon the deposited repair material to form a hard anodized coated component (60); providing a corrosion resistant sealant solution; and contacting a hard anodized coated component with the corrosion resistant sealant solution to form a corrosion resistant sealant coating on the hard anodized coated component (60).
