The Effect of Aging on the Corrosion Property of Al-7Si-0.3Mg

Abstract:

The effect of aging on the corrosion property of Al-7Si-0.3Mg Alloy immersed in 3.5% NaCl solution was studied by Tafel polarization curves and corrosion weight loss measurement in this paper. The Vickers hardness of the alloy during aging was measured on Zwick hardness testing machine. The electrochemical behavior of the Al-7Si-0.3Mg alloys after the under aged, peak aged and over aged were analyzed, respectively. The results show that the hardness of the alloy increases at first with the increasing of aging time and gets to the maximum at 4 hour, and descends gradually with the aging time (over aged). Icorr under peak aged status get to the highest value and to the lowest one during under aged status. Correspondingly, corrosion properties under peak aged status are the worst case and the best with under aged status.
