Abstract


The aim of this present work is to study the corrosion behavior of carbon steel in aqueous solution containing 60 ppm Cl- in the presence of 50ppmTris(hydroxymethyl)amino methane (THAM), 50 ppm of Zn2+ and 250 ppm of TSC solutions. Electrochemical, FTIR, UV spectral, SEM studies and weight loss study have been employed. THAM alone shows 52% IE was improved by Zn2+ and TSC. The synergistic effect of the inhibiting compound was calculated. Based on the above results a mechanism of corrosion inhibition is proposed. The surface morphology of the protective film on the metal surface was characterized by using Scanning Electron Microscope (SEM).
