Abstract
Some metals have natural oxide films in their normal state in contact with air. This natural film provides some protection, but because of its very low thickness, high porosity and low mechanical strength, has little practical value. Anodising, or anodic oxidation, is an electrolytic process, which artificially thickens this natural film by up to several hundred times, giving good corrosion protection and also favourable effects on certain mechanical, electrical and physicochemical properties.
