| description | This study looked into the influence of iron nitrate (Fe(NO<sub>3</sub>)<sub>3</sub> on the corrosion behavior of a 6061 Al alloy treated by a plasma electrolytic oxidation coating (PEO). PEO coatings were fabricated on Al alloy samples under AC conditions utilizing an alkaline-aluminate electrolyte containing 0 and 5 gr of Fe(NO<sub>3</sub>)<sub>3</sub>. Surface examination demonstrated that some Fe<sub>2</sub>O<sub>3</sub> particles were effectively integrated into the coating layer produced in a solution containing Fe(NO<sub>3</sub>)<sub>3</sub>. In addition, the porosity and the size of micropores made due to plasma activity were significantly reduced after the PEOO treatment of the 6061 Al substrate in an electrolyte containing Fe(NO<sub>3</sub>)<sub>3</sub>. Accordingly, the coating formed in the electrolyte with Fe(NO<sub>3</sub>)<sub>3</sub> exhibited superior corrosion resistance to that treated in the electrolyte without Fe(NO<sub>3</sub>)<sub>3</sub>. |
