Anodized aluminum is aluminum that has been treated to develop an exceptionally durable finish. To create anodized aluminum, you use an electrochemical process where the metal is immersed in a series of tanks, wherein one of the tanks, the anodic layer is grown from the metal itself.
To anodize aluminum, set up a plastic tub in a well-ventilated area and put your power supply on a non-flammable surface. Next, tie one end of a 12-gauge aluminum wire to your anode, wrap the middle of the wire around a piece of wood, and set a lead cathode on each side of the tub.
Anodized finishes have made aluminum one of the most respected and widely used materials today in the production of thousands of consumer, commercial and industrial products. Anodized Aluminum: Protects satellites from the harsh environment of space.
Aluminium alloys are anodized to increase corrosion resistance and to allow dyeing (colouring), improved lubrication, or improved adhesion. However, anodizing does not increase the strength of the aluminium object. The anodic layer is insulative. [3]
What is anodized aluminum? How does the anodizing process work? What are the benefits? This article answers these questions and more.
What is Aluminum Anodizing? Aluminum anodizing is an electrolytic process used to increase the thickness of the tightly adhering oxide layer that forms naturally on any aluminum surface exposed to air. The anodized layer has a porous, ordered structure.
Anodized aluminum is aluminum that has undergone an anodizing process to create a durable and protective oxide layer on its surface. This process involves immersing the aluminum in an electrolyte bath and applying an electrical current, which stimulates the formation of an oxide coating.
