| Abstract: | In this study, the corrosion susceptibility of aluminum matrix composites reinforced with artificially oxidized SiO2 and sol-gel Fe/TiO2 coated silicon carbide particles (SiCp) has been investigated. Corrosion behavior of the composites, fabricated by the liquid metal infiltration technique, was established in chloride containing alkaline environments by cyclic polarization (CP) and electrochemical impedance spectroscopy (EIS) techniques. It has been found that, sol-gel coating of SiC particles with Fe/TiO2 has a detrimental effect on the corrosion characteristics of A380-SiC metal matrix composite. |
