Corrosion Reasons and solution

Acids and bases are damaging to aluminium.The optimal pH value for the oxide layer is in the range 4 to 9.Acids and bases break down the oxide layer,thereby opening up the raw aluminium surface.If aluminium is exposed to very strong acid or alkaline environments outside the pH range 4 to 9,violent corrosion will occur in the form of metal pitting.Corrosion behaviour of aluminium in marineCORROSION BEHA-VIOUR OF ALUMINIUM UNDER CONTROL OF THE NATURAL FILM OF OXIDE Aluminium owes its excellent cor-rosion resistance to the presence on the metal of a permanent film of natural oxide that consists of alumina (Al 2 O 3) and makes the metal aluminum oxidationis corrosion#170;passive aluminum oxidationis corrosion#186; to the environ-ment.Although it is extremely thin,between 5 and 10 nanometers (3),
