A method of artificially thickening the oxide film on an aluminium alloy by an electrolytic process. The component to be treated is made the anode in a tank of electrolyte, and on the passage of electric current, oxygen is produced which reacts with the metal surface to form a tightly adherent oxide coating. Dyes may be added to the electrolyte to ...

A process of improving the corrosion resistance of aluminium by thickening the natural oxide film on the surface. The coating may be coloured with dyes or integrally in a few colours by tailoring the composition of the alloy treated.

The production of an oxide layer on aluminium alloys. The process is electrolytic, a typical electrolyte being sulphuric acid. Treatment at room temperature produces thin, decorative layers with some corrosion protection. Treatment at 0oC produces hard, thicker layers (up to 100µ) with wear resistance. They can be post sealed to give improved co...
