Abstract
Three aluminum-titanium carbide (Al-TiC) alloys were manufactured using mechanical alloying technique at 1300 ºC as sintering temperature. The effect of increasing the carbon content 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 remarkably increased with increasing the carbon content.
