Abstract

The inhibition efficiency of glycine-Zn2+ system has been evaluated by weight loss method and polarization study. Glycine alone has some corrosion inhibition efficiency (IE). In presence of Zn2+, IE increases. Synergistic effects exist between Zn2+ and glycine. The formulation consisting of 250 ppm of glycine and 50 ppm of Zn2+ has 86% IE. Polarization study reveals that this system function as mixed inhibitor system, controlling the anodic reaction and cathodic reaction to an equal extent
