However, carbon alloyed transition metal dichalcogenide (TMD-C) coatings possess low friction coefficients in diverse environments and can self-adapt to various sliding conditions. Hence, in this investigation, a semi-industrial magnetron sputtering device, operated in direct current mode (DC), is utilized to deposit several molybdenum-selenium-carbon (Mo-Se-C) coatings with a carbon content up to 60 atomic % (at. %). Then, the carbon content influence on the final properties of the films is analysed using several structural, mechanical and tribological characterization techniques. With an increasing carbon content in the Mo-Se-C films, lower Se\/Mo ratio, porosity and roughness appeared, while the hardness and compactness increased. Pin-on-disk (POD) experiments performed in humid air disclosed that the Mo-Se-C vs. nitrile butadiene rubber (NBR) friction is higher than Mo-Se-C vs. steel friction, and the coefficient of friction (CoF) is higher at 25 \u00b0C than at 200 \u00b0C, for both steel and NBR countersurfaces. In terms of wear, the Mo-Se-C coatings with 51 at. % C showed the lowest specific wear rates of all carbon content films when sliding against steel. The study shows the potential of TMD-based coatings for friction and wear reduction sliding against rubber.<\/jats:p>","DOI":"10.3390\/ma14061336","type":"journal-article","created":{"date-parts":[[2021,3,10]],"date-time":"2021-03-10T13:27:20Z","timestamp":1615382840000},"page":"1336","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["On the Microstructural, Mechanical and Tribological Properties of Mo-Se-C Coatings and Their Potential for Friction Reduction against Rubber"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8677-4677","authenticated-orcid":false,"given":"Jorge","family":"Caessa","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, CEMMPRE, University of Coimbra, Rua Lu\u00eds Reis dos Santos, 3030-788 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3610-5862","authenticated-orcid":false,"given":"Todor","family":"Vuchkov","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, CEMMPRE, University of Coimbra, Rua Lu\u00eds Reis dos Santos, 3030-788 Coimbra, Portugal"},{"name":"LED &amp; MAT\u2013IPN\u2014Laboratory for Wear, Testing and Materials, Instituto Pedro Nunes, Rua Pedro Nunes, 3030-199 Coimbra, Portugal"}]},{"given":"Talha Bin","family":"Yaqub","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, CEMMPRE, University of Coimbra, Rua Lu\u00eds Reis dos Santos, 3030-788 Coimbra, Portugal"},{"name":"LED &amp; MAT\u2013IPN\u2014Laboratory for Wear, Testing and Materials, Instituto Pedro Nunes, Rua Pedro Nunes, 3030-199 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8251-5099","authenticated-orcid":false,"given":"Albano","family":"Cavaleiro","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, CEMMPRE, University of Coimbra, Rua Lu\u00eds Reis dos Santos, 3030-788 Coimbra, Portugal"},{"name":"LED &amp; MAT\u2013IPN\u2014Laboratory for Wear, Testing and Materials, Instituto Pedro Nunes, Rua Pedro Nunes, 3030-199 Coimbra, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1016\/j.apsusc.2014.11.150","article-title":"Structure, tribological and electrochemical properties of low friction TiAlSiCN\/MoSeC coatings","volume":"327","author":"Bondarev","year":"2015","journal-title":"Appl.
