anodiseerimisel
Anodiseerimisel, also known as anodization, is an electrochemical process used to increase the thickness of the natural oxide layer on the surface of metal parts. It is most commonly applied to aluminum, but can also be used for titanium, magnesium, tantalum, and other metals. The process involves immersing the metal part in an electrolytic solution, typically sulfuric acid, and passing an electric current through it. The metal part acts as the anode, and the oxygen ions produced in the electrolyte combine with the metal atoms to form a thicker, more durable oxide layer.
The resulting oxide layer is integral to the metal substrate, meaning it is not a coating applied
