Abstract

In this study, the corrosion susceptibility of aluminum matrix composites reinforced with artificially oxidized SiO(2) and sol-gel Fe/TiO(2) coated silicon carbide particles (SiC(p)) 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/TiO(2) has a detrimental effect on the corrosion characteristics of A380-SiC metal matrix composite. (C) 2009 Elsevier Ltd.
