How to Anodize Aluminum wikiHow. Anodising of aluminium is an electrolytic surface treatment process where the work is made anodic in a acid solution. This is normally sulphuric acid, but this can be replaced with other acids for specialised coatings. The process is unlike other finishing methods. Where most processes coat the surface with an organic or inorganic deposit, anodising is a conversion of the base material itself, The Process of Anodising in outline: • an oxide of aluminium is formed on the surface of the aluminium after the aluminium is formed to shape - by turning rod, bending sheet, polishing, texturing a ….
