Effect of Copper and Silicon Carbide Content on the Corrosion Resistance of Al-Mg Alloys in Acidic and Alkaline Solutions

Abstract

In this study, corrosion resistance of cast aluminum based alloys and composites reinforced with silicon carbide has been investigated. Different Al-Mg-Cu alloys and Al-4wt.%Mg-Cu/SiC composites reinforced with 5 or 10 vol.%SiC were subjected to corrosive media (acidic: 1.0M HCl and alkaline: 1.0M NaOH) using weight loss method to evaluate their corrosion resistance.
