The present study investigates the physical and chemical characteristics, behavior in vitro vivo, biocompatibility of coatings containing Ta2O5, which are obtained by plasma electrolytic oxidation (PEO) on MA8 magnesium alloy. demonstrate vivo bioactivity. Compared to base PEO coating, layers Ta2O5 facilitate development apatite simulated body fluid, suggesting that inclusion nanoparticles improves bioactivity coatings. It was found incorporation increases roughness porosity formed...
In this study, a calcium-phosphate coating was formed on Mg–Mn–Ce alloy by the plasma electrolytic oxidation (PEO). The antibiotic vancomycin, widely used in treatment of infections caused Staphylococcus aureus (S. aureus), impregnated into coating. Samples with vancomycin showed high bactericidal activity against S. aureus. mechanical and electrochemical properties coatings were studied, as well vitro cytotoxicity tests vivo mature male rats performed. According to SEM, EDS, XRD XPS data,...
Bioactive coatings on VT1-0 commercially pure titanium were formed by the plasma electrolytic oxidation (PEO). A study of morphological features was carried out using scanning electron microscopy. composition investigated energy-dispersive spectroscopy and X-ray diffractometry analysis. It shown that PEO-coatings have calcium phosphate in their composition, which increases bioactivity surface layer. Electrochemical properties samples studied potentiondynamic polarization electrochemical...
Additive manufacturing has revolutionized implantology by enabling the fabrication of customized, highly porous implants. Surface modifications using electrochemical methods can significantly enhance bioactivity and biocompatibility biomaterials, including 3D-printed This study investigates novel coatings on 3D titanium (Ti) samples. Mesh Ti samples were designed subjected to plasma electrolytic oxidation (PEO) form a calcium phosphate coating. Subsequently, layer polydopamine (PDA) was...
In case of using titanium alloys in equipment exposed to aggressive media (for example, sea water), it is necessary take into account and, first all, prevent the formation a galvanic couple and another metal/alloy, which most cases leads corrosion destruction latter. Another significant problem its low wear-resistance poor tribological characteristics. To impart properties alloys, composite coating was formed on top titanium. For formation, combination plasma electrolytic treatment polymer...
The way of protective coatings formation on MA8 magnesium alloy by plasma electrolytic oxidation (PEO) in the electrolyte containing TiO 2 (B) nanoparticles has been developed. It is shown that coatings, which contain nanoparticles, have a significant advantage microhardenss and adhesive strength comparison with surface layers obtained without their use.
In this work, composite fluoropolymer-containing coatings were obtained on samples of AMg3 aluminium alloy, MA8 magnesium and VT1-0 commercially pure titanium treated by plasma electrolytic oxidation (PEO). Superdispersed polytetrafluoroethylene (SPTFE) a solution tetrafluoroethylene (TFE) telomers in acetone applied onto preliminarily formed PEO layers the spray-coating method. The contained large amount crystalline embedded outer porous layer coating did not have visible defects, which...
In the course of presented study, calcium phosphate coatings were formed on a mesh titanium endoprosthesis by plasma electrolytic oxidation (PEO). By scanning electron microscopy, it was established that resulting have developed morphology with significant number ports. Such coating structure may be favorable for cell adhesion. According to data XRD analysis, obtained contain α-Ca3(PO4)2 plasma-chemical synthesis surface layer. The presence this compound significantly increases affinity...
In this study, novel coatings were obtained on 3D Ti samples. The models of mesh samples designed. Then, a calcium phosphate coating was formed the by plasma electrolytic oxidation (PEO), which layer polydopamine (PDA) applied in next step. electrochemical properties, as well morphology coatings, studied. According to SEM, EDS, and Raman spectroscopy data, had developed contained phosphates, titanium dioxide, polymerized dopamine, indicates potential bioactive properties. During tests, an...
The paper presents results of investigation biocompatible coatings on VT1-0 commercially pure titanium formed using plasma electrolytic oxidation (PEO) method. effects samples with different surface treatment the functional activity cells innate immunity have been studied. study enzymes has showed higher stimulation cellular metabolism during first hour contact PEO-coating in comparison uncoated titanium. smallest immunostimulatory influence obtained for PEO-coating. It established that...
