Abstract
THE common technique for removing anodic oxide film from aluminium alloys is by dissolution of the metal substrate or attack along the metal–oxide interface using a bromine–methanol solution1,2, or a mercuric chloride solution3. Both these procedures are slower, offer more risk of contamination of the oxide and yield smaller pieces of intact film than the electrolytic detachment technique developed by Lacombe and Beaujard4.
