       In the discussion of anode anodization structures, some are usually first issued from structural models, allowing the reader to assume that this theoretical model is a simulation rather than a true objective image.

       The micropores of the porous anodized film are pore-shaped structures that are regularly perpendicular to the metal surface. First, make an image metaphor. Assuming that the thickness of the anodized film of sulfuric acid is 10 micrometers, since the diameter of the micropores is generally less than 20 nanometers, the diameter of the micropores is about 500 times or more, so this pore time should be said to be an elongated straight tube. The concept is very useful in future electrolytic coloring and sealing thinking. The density of micropores is even more striking, reaching 76 billion oxide film pores. It is said that the two-dimensional control on a thumb cover is 10 times that of the total population of the earth. Let us look at the oxide structure unit cell of the anodized film. Since the anodized film is an amorphous oxide, it cannot be called a cell, but is called a structural unit cell according to the national standard term. Metal scholars and structural analysis are often It is called a cell, and basically uses the term unit cell. The cell is the smallest structural unit of an amorphous and porous anodic oxide film. Among them, it is a circular hole, a fan-shaped barrier layer with a low through hole, and the cell wall is relatively dense. Liu Fang structure of aluminum oxide. Therefore, the unit cell of the aluminum anodized film can be compared to a pencil that goes to the center core, except that the ratio of the length of the unit cell to the diameter of the center hole is many times larger than that of the pencil.
