Recent research work of the inhibitory effect Schiff bases Salen, Salpr, Salcn on magnesium corrosion in hydrochloric acid 01/0 M has been studied. The magnesium samples previously prepared in a solution containing 01/0 M hydrochloric acid solution containing different concentrations of hydrochloric acid and Schiff base immersed corrosion test and the way Electrochemical the such as Polarization techniques, electrochemical impedance and electrochemical noise done. In this research, the results of polarization techniques, electrochemical impedance and noise have been analyzed and the results showed that the addition of three electrochemical methods are consistent with each other, With increasing inhibitor to the corrosive environment, the corrosion resistance is increased. In general it can be stated that the increase of Schiff base in the corrosive environment forming a protective layer on the magnesium sample this increases the corrosion resistance of magnesium, which is corrosive environments. Addition to a more detailed study of the effect of the SEM images were used.
