摘要：Summary Dextran, a biopolymer was used as an eco-friendly inhibitor to control the corrosion of 6061Al–15%(v) SiC(P) composite in 0.25M HCl medium. The electrochemical studies like potentiodynamic polarization method, electrochemical impedance spectroscopy techniques were adopted. Evaluation of kinetic and thermodynamic parameters was done. Inhibitor adsorption on the surface of the composite was confirmed by surface morphology studies like SEM and EDX studies. Maximum inhibition efficiency of 80% was obtained at 303K. Dextran acted as mixed type of inhibitor, underwent physical adsorption and followed Langmuir adsorption isotherm.
