Abstract

The as-received metal powders were used to synthesis bulk nanocrystalline Al; Al-10%Cu; and Al-10%Cu-5%Ti alloys using mechanical alloying and high frequency induction heat sintering. The corrosion of these materials in natural Arabian Gulf seawater (AGS) has been investigated using different electrochemical and spectroscopic techniques. The impedance spectroscopy measurements showed that the presence of Cu decreases the corrosion of Al and that effect was further reduced when adding Ti. Polarization experiments confirmed that adding Cu and Ti decreases the corrosion parameters for Al in AGS. Current vs.time at constant potential data indicated that Al suffers both uniform and pitting corrosion, which decrease in the presence of Cu and Ti. The surfance investigations confirmed the decrease of deterioration for Al surface containing Cu and Ti. All measurements were consistent with each other and indicated clearly that the corrosion resistance of these materials in AGS increases in the order Al-10% Cu-5% Ti > Al-10% Cu > Al.
