What term describes the electrochemical process used to form a durable, protective oxide layer on the surface of aluminum products?

Explanation

Anodizing is an electrochemical process used to thicken and strengthen the naturally occurring oxide layer on the surface of aluminum, improving its resistance to corrosion and wear while also allowing the surface to be dyed in various colors. This process is commonly used for aluminum products such as cookware, electronics casings, and architectural materials. Unlike galvanization, which adds an entirely different metal as a coating, anodizing enhances a protective layer made from the aluminum’s own natural oxide.
