The “Anodizing” is one of surface treatment techniques on a metallic material. It is widely applied for many kinds of metallic surface because of its excellent features: higher corrosion resistance, colorability, and insulation. It is also well-known as an applied technique to make many pores of less than 100 nm in diameter at a large metallic material. It is studied hard at companies, laboratories, and universities in order to establish how to control the pore's diameter, length, and density. The JEOL Ltd. can provide many advanced instruments to customers in all over the world to support their R&D activities. In this presentation, we will report analysis results of anodic oxide layers formed in an oxalic acid or sulfuric acid solution to reveal its own physical and chemical properties.
