The corrosion inhibition efficiency of α-brass was evaluated in unpolluted and sulfide polluted 3.5% NaCl. The Sodium (Z)-4-Oxo-4-p-Tolyl-2-Butenoate (SOTB) has been used as safe organic corrosion inhibitor instead of benzotriazole. The electrochemical methods were used to monitor the effect of inhibitor on corrosion inhibition of brass. The results showed that this inhibitor act as cathodic and anodic inhibitor for the surface of brass in both chloride and sulfide polluted medium. Brass electrodes were subjected to characterization by SEM and EDS to prove the probable mechanism. The inhibition efficiency and the persistence of protective film are depends on the inhibitor concentration in both chloride and sulfide media... View More»
