Due to the chemical reaction that occurred in the solid-state during processing, the produced samples were composed of an Nb-rich \u03b2-Ti phase that formed a metallic matrix along with Ti2C as a reinforcing phase. By employing different proportions of Ti:NbC, the phase composition of the alloys was designed to contain different ratios of \u03b1-Ti and \u03b2-Ti. The present work investigated the corrosion and tribocorrosion behavior of the composites, compared to unreinforced Ti, in a phosphate-buffered solution (PBS) at body temperature. Corrosion tests included potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Tribocorrosion tests were carried out using a ball-on-plate tribometer with sliding performed at open circuit potential (OCP) and under anodic potentiostatic conditions. Results showed that the stabilization of the \u03b2 phase in the matrix led to a decrease in the hardness. However, the formation of the in-situ reinforcing phase significantly improved the tribocorrosion behavior of the composites due to a load-carrying effect, lowering the corrosion tendency and kinetics under sliding. Furthermore, localized corrosion was not observed at the interface between the reinforcing phase and the matrix.<\/jats:p>","DOI":"10.3390\/met12060908","type":"journal-article","created":{"date-parts":[[2022,5,28]],"date-time":"2022-05-28T01:40:45Z","timestamp":1653702045000},"page":"908","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Improved Tribocorrosion Behavior Obtained by In-Situ Precipitation of Ti2C in Ti-Nb Alloy"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3464-9217","authenticated-orcid":false,"given":"Vin\u00edcius Richieri Manso","family":"Gon\u00e7alves","sequence":"first","affiliation":[{"name":"Department of Physics, School of Science, S\u00e3o Paulo State University (UNESP), Bauru 17033-360, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8212-874X","authenticated-orcid":false,"given":"Ihsan","family":"\u00c7aha","sequence":"additional","affiliation":[{"name":"Center for MicroElectroMechanical Systems (CMEMS-UMinho), University of Minho, 4800-058 Guimar\u00e3es, Portugal"},{"name":"Associate Laboratory on Biotechnology and Bioengineering, and Electromechanical Systems (LABBELS), University of Minho, 4800-058 Guimar\u00e3es, Portugal"},{"name":"International Iberian Nanotechnology Laboratory, Av.
