The basic materials analyzed in this study were five commercial Co\u2013Cr dental alloys with different components obtained in three processing steps. The analysis of the electrochemical behavior at the surface of the Co\u2013Cr alloys was performed by electrochemical measurements: impedance spectroscopy (EIS), open circuit electrical potential (OCP), and linear polarization (LP). In terms of validation, all five alloys had a tendency to generate a stable oxide layer at the surface. After the measurements and the graphical representation, the alloy that had a higher percentage of tungsten (W) and iron (Fe) in composition showed a higher tendency of anodizing. After the application of the heat treatment, the disappearance of the hexagonal phase was observed, with the appearance of new phases of type (A,B)2O3 corresponding to some oxide compounds, such as Fe2O3, Cr2O3, (Cr,Fe)2O3, and CoMnO3. In conclusion, the processing of Co\u2013Cr alloys by melting and casting in refractory molds remains a viable method that can support innovation, in the context of technology advance in recent years towards digitalization of the manufacturing process, i.e., the construction of prosthetic frameworks conducted by additive methods using Co\u2013Cr powder alloy.<\/jats:p>","DOI":"10.3390\/ma15093052","type":"journal-article","created":{"date-parts":[[2022,4,23]],"date-time":"2022-04-23T21:39:45Z","timestamp":1650749985000},"page":"3052","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Study on the Surface of Cobalt-Chromium Dental Alloys and Their Behavior in Oral Cavity as Cast Materials"],"prefix":"10.3390","volume":"15","author":[{"given":"Willi Andrei","family":"Uriciuc","sequence":"first","affiliation":[{"name":"Faculty of Dental Medicine, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adina Bianca","family":"Bo\u0219ca","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anida-Maria","family":"B\u0103b\u021ban","sequence":"additional","affiliation":[{"name":"Faculty of Dental Medicine, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9554-2715","authenticated-orcid":false,"given":"Hora\u021biu","family":"Verme\u0219an","sequence":"additional","affiliation":[{"name":"Faculty of Materials and Environmental Engineering, Technical University of Cluj-Napoca, 400641 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4158-3324","authenticated-orcid":false,"given":"Cecilia","family":"Cristea","sequence":"additional","affiliation":[{"name":"Faculty of Phrmacy, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400349 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2572-6724","authenticated-orcid":false,"given":"Mihaela","family":"Terti\u0219","sequence":"additional","affiliation":[{"name":"Faculty of Phrmacy, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400349 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petru","family":"P\u0103\u0219cu\u021b\u0103","sequence":"additional","affiliation":[{"name":"Faculty of Materials and Environmental Engineering, Technical University of Cluj-Napoca, 400641 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gheorghe","family":"Borodi","sequence":"additional","affiliation":[{"name":"National Institute for R&D of Isotopic and Molecular Technologies (INCEDETIM), 400293 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Suciu","sequence":"additional","affiliation":[{"name":"LIME-CETATEA, National Institute for R&D of Isotopic and Molecular Technologies (INCEDETIM), 400293 Cluj-Napoca, Romania"},{"name":"Electron Microscopy Center, Biology and Geology Faculty, Babes-Bolyai University, Clinicilor 5-7, 400007 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0360-016X","authenticated-orcid":false,"given":"Lucian","family":"Barbu-Tudoran","sequence":"additional","affiliation":[{"name":"LIME-CETATEA, National Institute for R&D of Isotopic and Molecular Technologies (INCEDETIM), 400293 Cluj-Napoca, Romania"},{"name":"Electron Microscopy Center, Biology and Geology Faculty, Babes-Bolyai University, Clinicilor 5-7, 400007 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u0103t\u0103lin Ovidiu","family":"Popa","sequence":"additional","affiliation":[{"name":"Faculty of Materials and Environmental Engineering, Technical University of Cluj-Napoca, 400641 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1033-0906","authenticated-orcid":false,"given":"Aranka","family":"Ilea","sequence":"additional","affiliation":[{"name":"Faculty of Dental Medicine, \u201cIuliu Ha\u021bieganu\u201d University of Medicine and Pharmacy, 400012 Cluj-Napoca, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Uriciuc, W.A.
