PITTING CORROSION OF HEAT-TREATABLE ALUMINIUM ALLOYS AND WELDS: A REVEIW

This review attempts to present the current understanding of the mechanism of pitting corrosion of heat treatable aluminium alloys and their welds. The role of alloying elements and intermetallic phases on the corrosion behavior of these alloys has been discussed. Pitting mechanism of aluminium- copper alloys is specifically discussed. Finally effect of welding on the pitting corrosion of these alloys is also presented.
