Anodising is the general name applied to methods of treating aluminium, where the work piece is made the anode in an electrolytic cell, usually to form oxide coatings for the purpose of increasing the performance of the surface.
Sulphuric Acid Anodising
Embraces anything from heavy duty black dyed coatings for high-tech instruments to cheap coloured ashtrays, expected to last in a pub for a few weeks. It also includes architectural anodising primarily for protecting aluminium window frames etc from the elements. The natural colour of these films is light grey; other colours are achieved by dyeing the film.
Is a branch of sulphuric acid anodising where process conditions have been pushed in a certain direction to achieve significantly harder, thicker, denser films. Applications involve resistance to wear, corrosion, temperature effects etc.
