• The oxidation rate of the pulse hard oxidation power is 10% higher than it of the common DC power.
• The oxidation film is better than common DC power in density, anti-corrosion, wear and temperature resistance, radiance and hardness.

• Different wave form output for multiple phases can be set.

Anodic oxidation is accomplished by immersing aluminum in an acidic electrolyte and running an electric current through the medium. The cathode is installed inside the anodic oxidation tank. Aluminum acts as an anode, so oxygen ions are released from the electrolyte and combine with the aluminum atoms on the surface of the anodized part. Therefore, anodic oxidation is a highly controlled oxidation problem – an enhancement of natural phenomena. Anodic oxidation is generally used to strengthen the product hardness, corrosion resistance and do surface treatment. One of the materials required to make a set of anodic oxidation equipment in addition to the anode tank, including the anode cathode, refrigerator, etc., rectifier is essential.

Anodic oxidation, electrochemical oxidation of metals or alloys. Aluminum and its alloy in the corresponding electrolyte and specific process conditions, due to the action of impressed current, aluminum products (anode) on the formation of a layer of oxide film process. Anodizing, unless otherwise specified, usually means anodizing sulfuric acid.

Aluminum’s inherent softness and susceptibility to surface damage pose significant challenges across engineering applications. These limitations demand surface enhancement solutions to boost durability while maintaining the metal’s advantageous properties. Among available technologies, anodizing emerges as the dominant industrial approach – a transformative electrochemical technique developed through decades of refinement.

This controlled oxidation process builds protective ceramic layers directly from the base metal. Engineers leverage these synthetic oxide structures to achieve combinations of corrosion resistance, architectural aesthetics, dielectric properties, and tribological performance unattainable with raw aluminum substrates.
