Cerium oxide (CeO2) is a potential corrosion inhibitor for aluminium, and titanium oxide (TiO2) is an efficient anti-fouling agent in the marine environment. The present study explored the possibility of incorporating CeO2 and TiO2 in aluminium to prepare a metal matrix composite that could have high corrosion and biofouling resistance under marine conditions. Such incorporation of CeO2 and TiO2 in pure aluminium offered high resistance to corrosion and biogrowth under marine conditions as evidenced during different tests. The specimens exhibited more anodic and stable open circuit potential throughout the period of the study. The optimum concentration of CeO2 and TiO2 was found to be 0.2 and 0.1%, respectively. The present results lay emphasis on the potential scope of the use of CeO2- and TiO2-incorporated aluminium in marine environments.
