摘要

Abstract

Corrosion inhibition characteristics of bio polymer dextran was studied for the corrosion control of 6061 Al-15%

HCl. Standard electrochemical techniques such as potentiodynamic polarization (PDP) measurements and electrochemical impedance spectroscopy (EIS) method were adopted for corrosion rate measurement. Surface morphology was studied by scanning electron microscopy (SEM) and elemental mapping was done by energy dispersive X-ray (EDX) analysis. Suitable mechanism was proposed for corrosion and inhibition process. Results indicated that dextran acts as an excellent anticorrosive agent for the corrosion control of 6061 Al-15%

at 303 K. Dextran acted as a mixed type of inhibitor

and got physically adsorbed both on composite and base alloy by obeying Langmuir adsorption isotherm. Dextran is proved to be a green inhibitor with environmental and economic benefits.
