Provided is a masking sheet for chemical solution treatment, the masking sheet comprising a substrate having first and second faces, and a PSA layer placed on the first face side of the substrate. The masking sheet is constituted so that penetration of a chemical solution is visually detectable when inspected from the outer face of the masking sheet.

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.

The present invention relates to a method for manufacturing an aluminum alloy anodized film having a superhydrophobic surface and an aluminum alloy having an anodized film with a superhydrophobic surface manufactured by the method. The present invention has an economical effect that an aluminum alloy, in which a three-dimensional shaped anodized film structure formed on the surface thereof is controlled in various forms, such as a pillar-on-pore structure, may be manufactured at low costs within a short time. The aluminum alloy with the controlled anodized film structure has excellent superhydrophobicity, corrosion resistance, and thermal conductivity, and thus may be used in various industrial fields, such as electronic device housings, LED lighting covers, heat exchangers, pipes, road structures, automobiles, aircrafts, ships, and generators.

An aluminum alloy is described and has compositions with mass percentage content consisting of: 5.0%-5.4% Zn; 0.9%-1.2% Mg; Cu<0.05%; Si<0.05%; Fe<0.1%; Mn<0.05%; Zr<0.1%; Ti<0.05%; other impurities <0.15%; and the remaining composition being Al. An anodizing method of the aluminum alloy described above is described and has: a degreasing treatment, a first black-film stripping treatment, a chemical polishing treatment, a second black-film stripping treatment, an anodizing treatment, a hole filling treatment and a drying treatment which are performed in turn. The aluminum alloy has a higher strength while eliminating an influence of a formed compound phase on a material texture.
