Notes:
The presence of a heavily deformed and corrosion susceptible surface/near-surface regionon rolled aluminium alloy has been amongst the most important problems which the aluminiummanufacturers are dealing with. While primarily the composition of the alloying elements and thethermo-mechanical treatment play an important role in determining surface activation, theimportance of several other secondary parameters cannot be ignored. This paper tries to identify theimpact of several factors, associated with sheet metal production, on the corrosion behaviour e.g. (a)type of the cast bar fed into the hot rolling mill, whether scalped or not scalped, (b) importance ofhomogenisation and in-line heat treatment, in relation to pre-existing understanding of surfaceactivation on AA3005, (c) effect of hot and cold rolling (d) effect of surface finish, etc. The alloyunder investigation was recycled AA5050, containing high Fe and Si as impurities, and usedcommercially for architectural purpose, eg. window facades
