Abstract
In this research, the aluminum terephthalate metal-organic framework (AlTp) and its two nanocomposites with graphene oxide (AlTp/GO) and iron oxide (AlTp/Fe2O3) were synthesized. The synthesized nanocomposites were then used as inhibitors to protect the AM60B magnesium alloy from corrosion in 30% ethylene glycol solution containing 0.5 M NaCl. The characterization of the proposed components was performed using FTIR and XRD spectra, as well as SEM images. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization were applied to investigate the inhibition abilities of the components in a concentration range of 50–400 ppm. Inhibition efficiencies obtained from EIS data were as 86.52%, 90.2%, and 90.8% for AlTp, AlTp/Fe2O3, and AlTp/GO, respectively. This trend was confirmed by polarization data. The results indicated that the incorporation of nanoparticles into the AlTp structure improved its inhibition performance. The adsorption isotherm and Gibbs free energy of the adsorption process were also determined and discussed.
