Appraisal Parameters of Corrosion Damage of Aged Aluminum Alloy Material

Abstract:

The corrosion fatigue character of aluminum alloy material was investigated. The aluminum alloy specimens were pre-corroded in different corrosive solutions and then were tested under fatigue load. The two key parameters of describing corrosion damage, surface corrosion damage ratio and average depth of corrosion damage, were analyzed using experimental observation and finite element method. The preliminary results indicated that the two key parameters could be the appraisal parameters for corrosion damage of aluminum alloy structure.
