2.Topological fine film3.Anodic aluminum oxide In 1936, Italian Caboni, he first proposed the patented electrolytic coloring of anodic aluminum oxide. The German Elssner further improved this method and applied for a patent in 1940. This makes the electrolytic coloring process the basis of the process. But it was in the midst of the chaos of the Second World War, and the chaos after the war made this process invention ignored for quite some time. Industrialization of Electrolytic Coloring In 1960, Asada Taiping improved and registered a patent for electrolytic coloring. The patent is characterized in that an alternating current is used as a power source, and the coloring solution is a salt of Co, Ni, Cu, Ag, Se, and their oxygen-containing salts as a main component. Asada has clearly identified several stages of the electrolytic coloring process. The metal ions are included in the micropores of the anodic aluminum oxide, and are converted into colored substances by electrolytic reduction. The global technology transfer right was obtained by ALCAN, and it was transferred to many countries around the world by its affiliated aluminum laboratory, Anolok-1, and the secondary electrolytic coloring method was popularized. During the 10 years from the mid-1960s to the mid-1970s, the research craze of electrolytic coloring was set off. Hundreds of patent documents were published each year, involving almost all soluble metal salts on the periodic table.is focused on Approved porous anodic alumina, |
