Protective Coating on Aluminum Alloy Created By Combined Solvothermal and Chemical Methods: Corrosion Test

This work demonstrate an in-situ solvothermal deposition of zirconium based metal-organic framework (MOF), UiO-66 derivatives on aluminum alloy. Such protection remarkably enhance the corrosion resistance and hydrophobic properties of the aluminum alloy. The observed corrosion resistance of the fabricated film was attributed to the resistant nature of the UiO-66 coating created on the alloy surface. SEM, FTIR, and XRD techniques were used to understand the microstructure and crystal structure of the designed composite materials. Electrochemical impedance spectroscopy (EIS) was used to assess the surface impedance.
