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.
