Abstract :
The electrochemical behavior of 6063 aluminum alloy in ethylene glycol-water mixture was investigated by
polarization curves and AC impedance measurements (EIS). The results obtained from polarization curves showed
that corrosion rate decreased with increasing ethylene glycol concentration. EIS data showed the decrease in the
interface capacitance which caused by adsorption of ethylene glycol at the surface of aluminum alloy. The cathodic
current increased with the increase in rotating speeds of solution and the anodic current decreased. The effect of
temperature was studied and the corrosion rate was increased with increasing the temperature. In addition,
thermodynamic parameters were calculated in different ethylene glycol concentrations.
