Strontium (Sr)-doped micro-arc oxidation (MAO) surfaces are proposed to improve biocompatibility and tribocorrosion resistance. This study examines the electrochemical behaviour of Ti surfaces treated with 0.0013 M and 0.13 M Sr-doped MAO via open circuit potential, potentiodynamic polarisation, and electrochemical impedance spectroscopy in a basic physiological solution at 37 \u00b0C. The results indicate that higher Sr concentrations led to lower passivation current densities (more than two times lower than at the lowest Sr concentration) and reduced barrier layer capacitance (more than one and a half times lower than at the lowest Sr concentration), suggesting improved corrosion resistance for Sr-enriched MAO treatments on Ti implants.<\/jats:p>","DOI":"10.3390\/met15040390","type":"journal-article","created":{"date-parts":[[2025,3,31]],"date-time":"2025-03-31T05:10:07Z","timestamp":1743397807000},"page":"390","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Electrochemical Evaluation of Strontium-Doped Micro-Arc Oxidation Surfaces on Titanium"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5054-9083","authenticated-orcid":false,"given":"Alexandra C.","family":"Alves","sequence":"first","affiliation":[{"name":"Department of Metallurgical and Materials Engineering, Faculty of Engineering, University of Porto, Rua Doutor Roberto Frias, 4200-465 Porto, Portugal"},{"name":"Associated Laboratory of Energy, Transports and Aerospace (LAETA), Institute of Science and Innovation in Mechanical and Industrial Engineering (INEGI), Rua Doutor Roberto Frias, 4200-465 Porto, Portugal"},{"name":"CMEMS-UMinho\u2014Center of MicroElectroMechanical Systems\u2014Universidade Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"given":"Carolina","family":"Dur\u00e3es","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, University of Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9138-9119","authenticated-orcid":false,"given":"Fatih","family":"Toptan","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Izmir Institute of Technology, 35430 Urla, Izmir, Turkey"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1225","DOI":"10.1007\/s10534-022-00438-w","article-title":"Feasibility study on Ti-15Mo-7Cu with low elastic modulus and high antibacterial property","volume":"35","author":"Cui","year":"2022","journal-title":"BioMetals"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Rodrigues, D.C., Robert, U.M., Jacobs, J.J., Gilbert, J.L., and Urban, R.M.
