Anodized coating is a special coating type of alumina. Aluminum is known as a durable metal. But in various corrosive environments aluminum resistance is not enough. For this reason, anodic coating of aluminum is required.

The chemical formula of the layer formed on the anodising aluminum is Al2O3

Aluminum surface, barrier layer and pore-like structure may be between 5-25 mm in thickness. In the process to be carried out later, these formed pores are closed in a way to be tightened to be a structure resistant to corrosive environments and heat. No matter how firm the anodic layer is, the formed pores must somehow pass through a chemical process
