Anodizing Definition

Anodizing Process

Anodizing is an electrochemical process that forms an oxide layer on the surface of aluminum alloys, which is commonly used to increase the corrosion resistance and durability of metal surfaces and create a decorative finish.

Anodizing is achieved by immersing the metal in a chemical bath containing an electrolyte, most commonly sulphuric acid. The anodizing process occurs at room temperature, producing thin layers with various colors and textures.

The main purpose of anodizing is to create a protective barrier that prevents corrosion by creating a film of aluminum oxide on the surface of the alloy. This film is extremely hard and durable, making it resistant to wear and tear.

It is important to note that the process does not add any material or change the structure of the metal. Instead, it changes its chemical composition, giving it better properties that make
