| Abstract | Plasma electrolytic oxidation (PEO) is a relatively novel surface finishing technique that converts the surface of light metals and alloys into oxide layers. For Al alloys, the coatings produced by PEO mainly consist of oxides with high hardness and therefore are more suitable for tribological applications than the substrate material. The PEO coatings can also effectively protect the base metal against corrosion. In this study ceramic coatings were deposited on 6061 Al alloy substrates using an alkaline electrolyte. The morphology, microstructure, compositions, and growth behavior of the coatings were analyzed using SEM, energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). The results suggest that the coating growth behavior is a function of the PEO process stages. This information can be used to better understand the PEO coating growth behavior and to improve the quality of the coatings for required applications. |
