Corrosion Behaviour of Aluminium-Iron (Al-Fe) Metal Matrix Composite (MMC) Reinforced with Silicon Carbide (SiC) Particles in Various Media Concentration of Tetraoxiosulphate IV Acid (H2SO4)

摘要

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.
