A study of the morphological features of coatings was carried out using scanning electron microscopy. A composition of formed coatings was investigated using energy-dispersive spectroscopy and X-ray diffractometry analysis. It was shown that PEO-coatings have calcium phosphate in their composition, which increases the bioactivity of the surface layer. Electrochemical properties of the samples were studied by potentiondynamic polarization and electrochemical impedance spectroscopy in different physiological media: simulated body fluid and minimum essential medium. The data of electrochemical studies indicate more than 15 times decrease in the corrosion current density for the sample with coating (5.0 \u00d7 10\u22129 A\/cm2) as compared to the bare titanium (7.7 \u00d7 10\u22128 A\/cm2). The formed PEO-layers have elastoplastic properties close to human bone (12\u201330 GPa) and a lower friction coefficient in comparison with bare metal. The wettability of PEO-layers increased. The contact angle for formed coatings reduced by more than 60\u00b0 in comparison with bare metal (from 73\u00b0 for titanium to 8\u00b0 for PEO-coating). Such an increase in surface hydrophilicity contributes to the greater biocompatibility of the formed coating in comparison with commercially pure titanium. PEO can be prospective as a method for improving titanium surface bioactivity.<\/jats:p>","DOI":"10.3390\/ma13184121","type":"journal-article","created":{"date-parts":[[2020,9,16]],"date-time":"2020-09-16T20:44:13Z","timestamp":1600289053000},"page":"4121","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":62,"title":["Bioactive Coatings Formed on Titanium by Plasma Electrolytic Oxidation: Composition and Properties"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9645-4936","authenticated-orcid":false,"given":"Dmitry V.","family":"Mashtalyar","sequence":"first","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"},{"name":"School of Biomedicine, Far Eastern Federal University, 690091 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantine V.","family":"Nadaraia","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"},{"name":"School of Biomedicine, Far Eastern Federal University, 690091 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9822-7849","authenticated-orcid":false,"given":"Andrey S.","family":"Gnedenkov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Igor M.","family":"Imshinetskiy","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariia A.","family":"Piatkova","sequence":"additional","affiliation":[{"name":"School of Biomedicine, Far Eastern Federal University, 690091 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4601-3232","authenticated-orcid":false,"given":"Arina I.","family":"Pleshkova","sequence":"additional","affiliation":[{"name":"School of Biomedicine, Far Eastern Federal University, 690091 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Evgeny A.","family":"Belov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valeriia S.","family":"Filonina","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"},{"name":"School of Biomedicine, Far Eastern Federal University, 690091 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergey N.","family":"Suchkov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"},{"name":"School of Biomedicine, Far Eastern Federal University, 690091 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0963-0557","authenticated-orcid":false,"given":"Sergey L.","family":"Sinebryukhov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergey V.","family":"Gnedenkov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Far Eastern Branch of the Russian Academy of Sciences, 690022 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"129","DOI":"10.1016\/j.surfcoat.2012.12.003","article-title":"Microstructure, corrosion and wear performance of plasma electrolytic oxidation coatings formed on Ti\u20136Al\u20134V alloy in silicate-hexametaphosphate electrolyte","volume":"217","author":"Cheng","year":"2013","journal-title":"Surf.
