Abstract
The corrosion inhibition of poly ethylene glycol (PEG) toward the aluminum surface in 1.0 M HCl has been studied by weight loss and polarization techniques. The results showed that the PEG acts as a good inhibitor and the inhibition efficiency is due to the anodic and cathodic inhibition (mixed type). The thermodynamic functions were calculated to find a good correlation with the inhibition efficiency. Quantum chemical parameters were calculated using ab initio and DFT methods to find a good correlation with the inhibition efficiency. A good correlation was found between the theoretical calculations and experimental observations.
