Ti and its alloys have been vastly employed in the manufacturing of biomedical implants for orthopedy and dentistry, especially the Ti-6Al-4V alloy (wt%), which is the most-used Ti alloy worldwide. However, the ion release of Al and V in the long term has been related to harmful effects on the human body. In this scenario, surface modification strategies, such as plasma electrolytic oxidation (PEO), have often been performed in Ti alloys to match the clinical needs. This study evaluated the effect of electrical AC parameters on the surface of the commercial Ti-6Al-4V alloy immersed in ZrO2-rich electrolytic solution regarding the chemical, physical, structural, and topographical aspects. Then, the selected PEO-treated samples surpassed the electrochemical test in saline solution. The results indicated that the electrical AC parameters affect the duration and intensity of the oxidative reactions and plasma micro-discharge steps, resulting in porous and thick oxide layers. PEO treatment promoted bio-camouflage of the surface, enriching it with TiO2, ZrO2, and ZrTiO4 compounds and depleting it of Al and V. After screening the PEO-treated samples and their corrosion behavior, the results indicated that the porous ZrO2–TiO2 ceramic coatings in the Ti-6Al-4V alloy can be a viable alternative for the manufacturing of biomedical implants.

<p>Due to the need to develop methods that optimize the surface properties of lightweight alloys such as aluminum, titanium, and magnesium and align with contemporary requirements of the 21st century, such as enhanced environmental and sanitary efficiency, the plasma electrolytic oxidation (PEO) process stands out as a comprehensive solution. This process can develop oxide coatings on the mentioned alloys, which exhibit superior physical and chemical properties compared with conventional methods. Since 2010, research in this area has been conducted with real-world applications. Recent studies have adopted experimental design approaches to optimize parameters to reduce operational costs and make the technology more accessible. The present study conducted a comparative analysis between treatments performed by conventional methods and by plasma processes, highlighting the most promising results.</p>
