Aluminum Fumarate Metal–Organic Framework: Synthesis, Characterization, and Application as a Novel Inhibitor against Corrosion of AM60B Magnesium Alloy in Ethylene Glycol Solution
2021
The aluminum fumarate metal–organic framework (MOF) was synthesized for the application as a corrosion inhibitor of AM60B magnesium alloy in 30% ethylene glycol solution containing 0.5 M NaCl. The prepared MOF was characterized using the XRD and FTIR spectra, as well as SEM images and TGA. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques were used to evaluate the inhibitor performance in a concentration range of 50-400 ppm. The results indicated that the inhibition efficiency enhanced with increasing inhibitor concentration and reached 88.35% at 400 ppm, indicating the high potential of the proposed MOF.
