Abstract: The pure Al matrix composites reinforced with micro-Ti (Ti) particles as well as microAl2O3 (MA) or nano-Al2O3 (NA) particles have been developed via powder metallurgy route. Corrosion tests in aqueous 3.5 wt.% NaCl solution at neutral pH have been carried out. The same has also been investigated for the Al composites reinforced with these particles alone i.e., Ti, MA, NA. The hybrid composites i.e., Al+Ti+MA and Al+Ti+NA exhibited relatively inferior response to corrosion as compared to the composites Al+Ti, Al+MA and Al+NA. The particles are considered as defects in the passive film. Thus, it is difficult to build a dense passive layer free from defects in case of the composites reinforced with higher volume fraction of ceramic and metallic particles.
