Abstract
An aluminum member exhibits improved alkali resistance with respect to an anodic oxide coating. The highly alkali-resistant aluminum member includes a material that includes aluminum or an aluminum alloy, an anodic oxide coating that is formed on the surface of the material, and a coating layer that is formed on the anodic oxide coating, and includes a siloxane glass component in a ratio of 90 mass % or more, wherein the coating layer has a thickness of 0.5 to 5.0 μm and a coating mass of 0.4 to 5.0 g/m 2 .
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A highly alkali-resistant aluminum member comprising:
a material that comprises aluminum or an aluminum alloy; an anodic oxide coating that is formed on a surface of the material; and a coating layer that is formed on the anodic oxide coating, and comprises a siloxane glass component in a ratio of 90 mass % or more, wherein the coating layer has a thickness of 0.5 to 5.0 μm and a coating mass of 0.4 to 5.0 g/m 2 .
2 . The highly alkali-resistant aluminum member as defined in claim 1 ,
wherein the anodic oxide coating is a sulfuric acid electrolytic coating or an oxalic acid electrolytic coating that has been subjected to a hot water treatment or a semi-sealing treatment.
3 . The highly alkali-resistant aluminum member as defined in claim 1 ,
wherein the anodic oxide coating is a colored coating.
4 . The highly alkali-resistant aluminum member as defined in claim 2 ,
wherein the anodic oxide coating is a colored coating.Cited by (0)
