Abstract
A series of aluminum-titanium carbide (Al-TiC) alloys was manufactured using mechanical alloying technique at different sintering temperatures, namely 900, 1100, and 1300 ºC. The effect of sintering temperature on the corrosion of these alloys in 3.5% NaCl solutions was investigated using cyclic potentiodynamic polarization, chronoamperometric current-time, open-circuit potential, and electrochemical impedance spectroscopy measurements. The surface of the alloys after their corrosion in the test solution was investigated using scanning electron microscopy investigations. All results were consistent with each other and confirmed clearly that the corrosion resistance of Al alloys decreased with increasing the sintering temperature.
