MgAl Oxide Coatings Modified with CeO2 Particles Formed by Plasma Electrolytic Oxidation of AZ31 Magnesium Alloy: Photoluminescent and Photocatalytic Properties

Опубликована: Март 6, 2024

MgAl oxide coatings containing MgO and MgAl2O4 phases were doped with CeO2 particles using plasma electrolytic oxidation (PEO) of AZ31 magnesium alloy in 5 g/L NaAlO2 water solution, added at concentrations up to 8 g/L. They underwent extensive inve-stigation into their morphology, chemical phase compositions, most importantly, photoluminescent (PL) properties photocatalytic-activity (PA) photodegradation methyl orange (10 cm3 mg/L). The concentration the aluminate electrolyte influences amount incorporated coatings, but have no signi-ficant effect on surface thickness, or structure coatings. PL emi- ssion spectrum coating is divided two bands: one 350-600 nm range related structural defects MgO, another much more intense 600-775 attributed F+ centres MgAl2O4. Incorporated do not a significant intensity band red spectral region, first increases particles. PA MgAl/CeO2 higher than that pure highest was observed for formed electrolytes addition 2 remained chemically physically stable across multiple cycles, indicating potential applications.

Implant surgeries are increasingly challenging due to their rising number. Achieving the desired biomaterial surface properties ensure a strong bond with human tissue is significant issue. This study investigates influence of ultrasound (US) during micro-arc oxidation (MAO) process on Ti13Zr13Nb bio-alloy, an area not previously explored, enhance titanium alloy coatings' for biomedical applications. Porous calcium-phosphate-based coatings were successfully deposited using MAO and (UMAO). Various such as morphology, chemical composition, topography, wettability, free energy, thickness, adhesion substrate, well mechanical corrosion characteristics thoroughly analyzed. Cytocompatibility was assessed osteoblasts. Using US increased coating roughness (up ~ 17%), core height 22%), isotropy thickness 46%), hardness 18%), depending parameters mode. Optimal performance achieved at 136 mA, 600 s, sinusoidal setting, resulting in highest (~ 79%) rutile quantity (2.6%), lowest elastic modulus 57 GPa), contact angle 70°, all which could have contributed enhancing osteoblast viability vitro. study, first time, underscores importance tailoring specific
