Abstract
The effect of N-thiazolyl-2-cyanoacetamide derivatives on the corrosion of aluminum in 0.01N sodium hydroxide has been studied using weight-loss and glvanostatic polarization techniques. The inhibition efficiency was found to increase with increasing the concentration of inhibitor and with decreasing temperature. The inhibition process was explained in terms of its adsorption on the aluminum surface The adsorption is obeyed Frumkin isotherm. The addition of Ba2+, Sr2+, Ca2+ and Mg2+ ions to N-thiazolyl-2-cyanoacetamide derivatives enhanced the inhibition efficiency due to synergistic effect. Polarization data suggested that the additives used as mixed type inhibitors. Some activated thermodynamic parameters were calculated and explained.
