Plasma electrolytic oxidation (PEO) is a process for obtaining oxide coatings on valve metals, primarily conducted in aqueous electrolyte solutions that limit treatment sizes due to overheating. The objective of this study was to investigate an alternative method for PEO processing of aluminum 1050 alloy using nitrate molten salt. The methodology involved examining the morphology, phase and chemical compositions, micro-hardness, and corrosion resistance of the coatings formed. Results indicated the presence of a two-layer coating, comprising an outer soft layer of 4 µm and a denser inner layer of 5 µm. The formed coatings were found to consist of corundum, γ-Al2O3, and θ-Al2O3, showing promising characteristics without contamination from the electrolyte. These findings suggest that PEO processing in nitrate molten salt offers a viable method for enhancing the protective properties of aluminum alloys, addressing limitations in chemical resistance and expanding their application in various industries.
