  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. The results show that introducing copper and silicon carbide have a negative effect on the corrosion resistance of monolithic aluminum; however, Al-based composites still being attractive materials to replace steel parts in automotive and aircraft industries and hence studying their corrosion resistance is of high importance. Scanning electron microscopy (SEM) and Energy-dispersive X-ray (EDS) were used to show the degree of attack and of acidic and alkaline solution on the surface of the investigated materials.
