Background

Anodized aluminum is a layer of dense aluminum oxide on the surface of aluminum or aluminum alloys, which has the same chemical properties as aluminum oxide in order to prevent further oxidation. However, unlike conventional oxide films, anodized aluminum can be dyed by electrolytic coloring, and the anodic effect occurs because oxygen-containing ions in the electrolyte gradually decrease as the electrolytic process proceeds, and when a certain degree is reached, fluorine is precipitated and reacts with the anodic carbon to form carbon fluorides, which precipitate fine carbon particles upon decomposition, which attach to the surface of the anode and prevent the electrolyte from contacting the anode, so that the electrolyte does not wet the anode well, and as water does not wet the surface coated with oil, a gas film with poor conductivity is formed between the electrolyte and the anode, and the anodic overvoltage increases, causing the anodic effect. When new alumina is added, oxygen is separated out on the anode and reacts with the carbon powder to gradually make the surface of the anode quiet, the resistance is reduced, and the electrolysis process tends to be normal.
