The inhibition effectiveness of Alanine - Zn2+ system in scheming deterioration of carbon steel in salt water has been evaluate by mass loss method. The formulation consisting of 250 ppm of Alanine and 25 ppm of Zn2+ has 87% IE. A synergistic effect exists among Alanine and Zn2+. Polarization analysis reveals to facilitate the Alanine - Zn2+ system function as an anodic inhibitor and the formulation controls the anodic reaction mostly. The character of the shielding film on metal shell has been analyzed by AFM analysis.
