20.500.12556/DiRROS-20536 Influence of the oxidizing technique on the biocompatible and corrosion properties of Ti6Al4V in a physiological environment This work aims to evaluate the corrosion and biocompatibility properties of oxide films generated on Ti6Al4V alloys using both traditional and novel methods. Oxide films were generated by anodization and plasma treatment to achieve a blue surface finish. The oxide films were then characterized and compared to a native film formed on the Ti6Al4V. Electrochemical tests, incorporating potentiodynamic tests and electrochemical impedance spectroscopy, were employed to define the electrochemical resistance of oxides in an environment simulating biological exposure. In vitro tests were conducted to study ion release and biocompatible properties over a 6-week period of exposure to a 0.9 wt% NaCl solution, at body temperature. Various spectroscopic techniques, including ToF-SIMS, XRD, and Raman analysis, were used to study the structure and chemistry of the oxide films. The sub-surface layer was analysed by microstructural investigation. The type of oxidation was found to have a key influence on the oxide composition, especially with respect to the depth distribution of the individual alloy elements through the oxide film. The oxidation process determines which of the alloying elements are released into the environment, as a result of the corrosion reactions. oxide film biocompatibility surface characterization ion release simulated body fluid oksidni film biokompatibilnost površinska karakterizacija sproščanje ionov simulirana telesna tekočina true false true North-Holland Angleški jezik Slovenski jezik © 2024 The Author(s) Neznano 2024-10-16 12:00:13 2024-10-16 12:07:22 2026-02-19 07:01:36 0000-00-00 00:00:00 2025 0 0 str. 1-13 [article no.] 161486 Vol. 681 Feb. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-10-10 544.5/.6 1873-5584 10.1016/j.apsusc.2024.161486 211400195 https://www.sciencedirect.com/science/article/pii/S0169433224022013 1 7080db21-8ba5-11ef-89f3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28964 RAZ_Bajt_Leban_Mirjam_2025.pdf RAZ_Bajt_Leban_Mirjam_2025.pdf 1 5DFBEDED188F803C31B0C4D62080DF4F 7ab6a39021fe590203879ac9981adbbf1c3b654da1ae2c6feb9a66fee245441f 54ff21b9-8ba6-11ef-89f3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28965 RAZ_Bajt_Leban_Mirjam_2025.docx RAZ_Bajt_Leban_Mirjam_2025.docx 1 0162081E90C329E4A441B74D7329DDA6 0cf60fcab6c1a7ee1fda3d0fc572f0899ca50ecec9796cda1c267a74732a283f 611538fb-8ba6-11ef-89f3-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=28966 Zavod za gradbeništvo Slovenije 0 0 0
