Summary: The study showed that sealing plasma electrolytic oxidation (PEO) coatings on AZ91 Mg alloy in calcium nitrate solutions at different pH values can enhance the corrosion resistance of the coatings. Adding SDS facilitates the formation of precipitates, resulting in hydrophobic coatings with poorer paint adhesion but better corrosion resistance.

Summary: Dental implants made from titanium and its alloys are commonly used due to their inertness and biocompatibility. However, to improve their success rate, it is necessary to enhance the integration with bone and gum tissues and prevent bacterial infections. Various surface modification techniques, including plasma electrolytic oxidation (PEO), have been explored. In this study, the use of nitrilotriacetic acid (NTA) as a complexing agent in the PEO process was found to improve the corrosion resistance of titanium implants and reduce bacterial colonization.

Summary: The corrosion resistance of austenitic stainless steel (SS) has been significantly improved by the cathodic plasma electrolytic oxidation (CPEO) process, which forms a protective oxide layer. This process creates two distinct layers on the SS surface: a porous outer layer of Fe oxides and a compact inner layer of Cr oxides. The thicknesses of the outer and inner layers are approximately 7 μm and 12 μm, respectively, and the oxide layers are fabricated in a short time of less than 30 seconds. Potentiodynamic polarization analysis showed a 65% decrease in corrosion current after the formation of the protective oxide layer, confirming the effectiveness of the CPEO treatment. Electrochemical impedance spectroscopy revealed that the outer layer captured corrosive species due to its porous structure, while the compact structure of Cr oxides in the inner layer provided high resistance to reactions with corrosive species. Additionally, a Rockwell C indentation test demonstrated the strong mechanical property and bonding strength of the protective oxide layer to the substrate.

Summary: By using the PEO process in galvanostatic mode, magnesium oxide coatings (up to 182 μm) were successfully produced on AZ63 alloy. XRD, XPS, and SEM were used to evaluate the coatings' structure, chemical composition, and morphology. The results showed that mixed-crystalline magnesium oxide formed porous PEO layers with increased hardness and improved corrosion resistance on pure AZ63 alloy, with values of 26.9 GPa and 2.0 μA/cm2 indicating noticeable performance characteristics.

Summary: The PEO treatment time affects the thickness and surface morphology of the plasma electrolytic oxidation coating, but does not significantly affect the phase composition. The additional addition of anatase particles can increase the amount of anatase in the coatings, but has minor effect on corrosion resistance while reducing wear resistance remarkably.

Summary: The aim of this study is to investigate the effectiveness of chromophoric organic compounds in modifying the surface of AZ31 Mg alloy using the plasma electrolytic oxidation (PEO) process. The deposition of cochineal extract and indigotin extract on PEO coatings and their impact on the morphology, structure, and properties of the resulting coatings were examined. The results indicate that the deposition of cochineal extract leads to a smoother surface morphology, while indigotin deposition results in a partially sealed surface with large cracks.

Summary: In this study, a two-step treatment involving SiO2 gel and hexadecyltrimethoxysilane was used to modify PEO coatings on AZ91 alloy. The treatment effectively sealed the microholes in the PEO coating, resulting in a dense coating with improved hydrophobicity. The corrosion resistance of the substrate alloy was significantly enhanced, making it a promising approach for post-treatment of PEO coatings.

Summary: The incorporation of TiC NPs significantly improved the hardness, effective elastic modulus, wear resistance, and corrosion resistance of the oxide layer, while also increasing the layer thickness. This enhancement was attributed to the chemically inert incorporation of particles and an increase in layer crystallinity.

Summary: Plasma electrolytic fluorination (PEF) was conducted on AZ31 Mg alloy in ethylene glycol (EG) electrolytes with varying amounts of H3PO4. The effects of H3PO4 addition on the microstructure, growth behavior, and corrosion resistance of the PEF coatings were investigated. The results showed that the addition of H3PO4 weakened the plasma discharges and decreased the crystallinity of the PEF coating. When the H3PO4 content reached 20 g/L, the PEF coating transformed into an amorphous state. Furthermore, adding H3PO4 into the EG electrolytes increased the growth rates of the PEF coatings and changed the growth mechanism from inward growth to mixed growth dominated by outward growth. The corrosion resistance of the PEF coating varied with the H3PO4 content in the EG electrolytes, with the best corrosion resistance observed at an H3PO4 content of 10 g/L.
