Method of forming a colored and oxide film on aluminum and aluminum alloys |
摘要 |
A method in which aluminum and aluminum alloys are subjected to anodic oxidizing treatment by use of a novel electrolyte to form a good colored and oxide film on the surface thereof. The electrolyte comprises an organic acid solution resulting from the sulfonation of fumaric acid (hereinafter tentatively referred to as the sulfofumaric acid) as a main liquid, into which either oxalic acid as an organic acid, or sulfuric acid or metal sulfate as the inorganic acid are added.
