Anodic oxidation includes both aluminum anodizing and hard anodizing. Anodic oxidation (anodic oxidation), electrochemical oxidation of metals or alloys. The process of forming a layer of oxide film on aluminum products (anodes) under the action of an applied current in aluminum and its alloys under the corresponding electrolyte and specific process conditions. The so-called anodic oxidation of aluminum is an electrolytic oxidation process in which the surface of aluminum and aluminum alloys is usually transformed into a layer of oxide film, which has protective, decorative and some other functional properties.

Ordinary decorative anodizing requires a DC power supply voltage of usually 20V-24V, while hard anodizing usually has a higher voltage depending on the process, sometimes reaching 80V, 100V, 120V, etc. The current is determined by the size of the workpiece to be anodized, ranging from a few hundred amps to tens of thousands of amps.

Aluminum oxidation coloring, using artificial methods to make aluminum and its alloy products surface to generate a layer of oxide film (Al2O3) and apply different colors, in order to improve the wear resistance of aluminum, prolong the service life and increase the color and beauty. The basic process of oxidation coloring is aluminum surface treatment, oxidation, coloring and subsequent hydration sealing, organic coating and other treatment processes. The coloring methods of oxide film are chemical coloring, electrolytic coloring and natural coloring, etc.
