In thisstudy, the corrosion susceptibility of aluminium matrix composites reinforced with sol-gel TiO 2 -coated silicon carbide particles has been investigated. The corrosion of the composite, fabricated by means of aliquid metal infiltration technique, was established in chloride-containing alkaline environments using the potentiodynamic polarisation technique. Microstructural and interfacial characterisation of the composite was carried out by using an optical microscope, scanning electron microscope, energy dispersion spectroscopy and X-ray diffractometer. The corrosion performance and its effect on the compositem icrostructure are discussed in relation to previous observations. B.
