Abstract

Dextran, a biopolymer was used as an eco-friendly inhibitor to control the corrosionof 6061Al—15%(v)SiC(P)composite in 0.25 M HCl medium. The electrochemical studies like poten-tiodynamic polarization method, electrochemical impedance spectroscopy techniques wereadopted. Evaluation of kinetic and thermodynamic parameters was done. Inhibitor adsorptionon the surface of the composite was confirmed by surface morphology studies like SEM and EDXstudies. Maximum inhibition efficiency of 80% was obtained at 303 K. Dextran acted as mixedtype of inhibitor, underwent physical adsorption and followed Langmuir adsorption isotherm.© 2016 Published by Elsevier GmbH.
