Abstract

Aluminium and aluminium alloy treatment consists of depositing an electrically insulating material on its surface at short distances and subsequently submitting the aluminium or -alloy to anodic oxidation whilst the insulation remains intact and an oxide layer of locally different thickness is formed on the surface.
