Abstract

The current study focused on the investigation of the corrosion behaviour of aluminium-iron (Al-Fe) Metal matrix Composite (MMC) reinforced with silicon carbide (SiC) particles in various media concentration of tetraoxosulphate iv acid (H2SO4). The Al/Fe materials were combined in the various proportion of 10% wt Al/87.5% wt Fe, 15%wt Al/80% wt Fe and 20%wt Al/73% wt Fe respectively. They were fed into an electric furnace and mechanically stirred to form a fine vortex. The respective molten compositions were reinforced with silicon carbide (SiC) particles. The fabricated composite were of the composition; 2.5% SiC/10% wt Al / 87.5% wt Fe, 5%wtSiC/15%wt Al/80% wt Fe and 7%wt SiC/20%wt Al/73% wt Fe. The materials were subjected to weight loss analysis and the results were analyzed using regression analysis. Micro-structural scans showed signs of porosity and the weight loss corrosion test result expressed reduction in corrosion resistance with SiC addition.
