Anodizing of aluminum 6061 alloy with incorporated nanoparticles to inhibits the aluminum corrosion

In this work, Aluminum alloy 6061 (A6061) was modified by Anodizing and incorporating with ZnO and Fe3O4 nanoparticles to improve its corrosion-resistant. The titanium sheet was used as a counter electrode and the DC voltage reach 20 mV while the anodizing solution was 20% H2SO4 while the H2SO4 was mixed with the two Oxide nanoparticle to incorporate the AA6061 surface. Anodizing and incorporation with (ZnO and Fe3O4) NPS were confirmed by X-ray diffraction. The surface morphology of anodized and incorporated surface was examined through scanning electron microscopy (SEM). Modified A6061 by Anodizing and nanoparticle incorporation revealed a good corrosion protection efficiency even at temperatures ranging (298-328) K in a saline medium. Where the corrosion current density increase with the increase in temperature. Activation energy and pre-exponential factor (kinetic parameters) were calculated and discussed. Also, thermodynamic values ?G* and ?H* were calculated.
