Anodizing - Wikipedia

Anodizing (also spelled anodising in British English) is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called anodizing because the part to be treated forms the anode electrode of an electrolytic cell .

Surface treatment with anodising

Aluminium item anodised in 4 different colors. Electrochemical surface treatment, also referred to as anodising, is a process of increasing the natural oxide layer formed on the aluminium surface when it comes in contact with oxygen. The oxide layer is increased by means of electrical current, which makes the aluminium surface more durable.
