In this study, the pitting susceptibilities of Al-Cu alloy based metal matrix composites (MMCs) reinforced with boron carbide (B4C) particles have been investigated using cyclic polarization (CP) technique in aerated and deaerated 3.5 wt.% NaCl solution. The effects of reinforcement particle volume fraction and artificially aged (T6) process on corrosion behaviour of the composites have been also examined. It has been found that the 30 % B4C MMC is more susceptible to pitting attack compared with 10 % B4C MMC.
