Fabrication, properties and biological activity of a titanium surface modified with zinc via plasma electrolytic oxidation

To improve the biological activities of titanium implant surfaces and promote efficient early bone formation, formation bioactive coatings that on is currently an important area research. In this study, we prepared a zinc-doped porous coating (Zn-PEO) alloy surface via plasma electrolytic oxidation. The characteristics samples were evaluated with field emission scanning electron microscopy (FE-SEM), X-ray photoelectron spectroscopy (XPS), profilometry, static contact angles nanoscratch studies. slow release zinc from was detected inductively coupled plasma‒mass spectrometry (ICP‒MS). corrosion resistances electrochemical On basis, biocompatibility activity sample through in vitro cell experiments. results confirmed Zn-PEO successfully alloy; it exhibited micro/nanomorphology, substrate tightly bound. increased roughness improved wear resistance. More importantly, promoted adhesion, proliferation, differentiation mineralization marrow mesenchymal stem cells had good activity. Therefore, structures implants properties has application prospects.
