Inhibitive action of glutathione reduced on the deterioration of aa6061 in 0.5m HCL

Research output: Contribution to journalArticle

Abstract

Corrosion inhibitive action of glutathione reduced (Gth), an eco-friendly inhibitor of aluminium alloy 6061 (AA6061) was investigated in a 0.5 M HCl medium. Experiments were conducted using weight loss and potentiodynamic polarization (PDP) methods. The inhibition efficiency of Gth increases with increasing its concentration and decreases with increasing temperature. Gth demonstrated reasonably good inhibition performance (87 % at 0.7 mM at 303 K) by acting as a mixed inhibitor. The measurement of activation and thermodynamic parameters regulating the inhibition behavior of Gth shows the mixed adsorption of Gth on the alloy surface, which follows the Langmuir isotherm model. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) was used to conduct the surface morphological examination of corroded and inhibited alloy specimens.
