Aluminum conductive member and method for producing same
Provided are an aluminum conductive member that includes an electrical connection portion excellent in conductivity and rust resistance and an electrical insulation portion excellent in long-term durability, chemical resistance, and the like, and can be manufactured at low cost, and a method of manufacturing the same. Specifically, provided are an aluminum conductive member, including: an aluminum conductive base material formed of an aluminum material including aluminum or an aluminum alloy; an electrical connection portion formed in a region of the aluminum conductive base material, the electrical connection portion having a surface coated with a conductive oxidation preventing film and being used as a terminal; and an electrical insulation portion formed in a region of the aluminum conductive base material other than the region in which the electrical connection portion is formed, the electrical insulation portion being coated with an anodic oxide film, and a method of manufacturing the same.
OIL-IMPREGNATED NANOPOROUS OXIDE COATINGS HAVING BOTTLE-SHAPED PORES
A method for creating oil-filled porous anodic oxide coatings for metallic surfaces is disclosed. The coating has anti-corrosion and omniphobic properties to resist both underwater and atmospheric conditions. To realize oil-impregnated three-dimensional bottle-shaped pores in the oxide layer in anodizing aluminum, the following steps may be taken. First, the target surface may be cleaned and electropolished. Then, a first anodizing step at a lower voltage is applied to create relatively small-diameter pores in the entrance (i.e., top) region of the oxide layer, followed by a second anodizing step at a higher voltage to subsequently create larger-diameter pores in the base (i.e., bottom) region of the oxide layer. Pore widening follows to enlarge the overall pore diameters. To fill the porous coating with an oil, a solvent exchange method may be utilized.

PROCESS FOR ENHANCED CORROSION PROTECTION OF ANODIZED ALUMINUM
Processes for enhancing the corrosion resistance of anodized substrates are disclosed. In some embodiments, the process involves a second anodizing operation that targets an area of the substrate that is left inadequately protected by a first anodizing operation, and also targets defects that may have been arisen from intermediate processing operations such as laser-marking operations. The second anodizing operation can be conducted in a non-pore-forming electrolyte, and grows a thick protective barrier film over inadequately protected areas of the substrate, such as laser-marking treated areas.
