Latest Patents

Shinji Hayashi holds a patent for a process titled "Process for electrolytically coloring aluminum and aluminum alloys." This patent describes a method where aluminum or aluminum alloy is first anodized to form an oxide film. Before being colored electrolytically in an electrolytic solution, the anodized basis metal is made anodic in this solution, and direct current is passed through it. The basis metal is then electrolyzed in the same solution using alternating current for the actual coloring operation. The electrolytic solution contains at least two metallic salts, with or without a strongly reducing compound. This innovative process enhances the durability and aesthetic appeal of aluminum products.
