Biotribological tests were performed in a ball-on-plate geometry using an alumina ball as the counter body under a phosphate-buffered saline solution at 37 \u00b0C, assessing the coefficient of friction and specific wear rate. Hardness measurement, white-light interferometry, and scanning electron microscopy were employed to support the study. The results revealed that the carbon nanotubes exhibited a positive influence on the biotribological behavior resulting in 1 wt% CNT proved to be the optimized value. Such findings could engineer high-performance surfaces as load-bearing materials in biomedical applications.<\/jats:p>","DOI":"10.1088\/2631-8695\/ac77db","type":"journal-article","created":{"date-parts":[[2022,6,10]],"date-time":"2022-06-10T18:27:18Z","timestamp":1654885638000},"page":"035002","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Effect of carbon nanotubes on the biotribological behavior of hot-pressed PEEK-based composites for biomedical applications"],"prefix":"10.1088","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4962-9729","authenticated-orcid":true,"given":"T","family":"Pigosso","sequence":"first","affiliation":[]},{"given":"V","family":"Richhariya","sequence":"additional","affiliation":[]},{"given":"C","family":"Binder","sequence":"additional","affiliation":[]},{"given":"F S","family":"Silva","sequence":"additional","affiliation":[]},{"given":"O","family":"Carvalho","sequence":"additional","affiliation":[]},{"given":"J R","family":"Gomes","sequence":"additional","affiliation":[]}],"member":"266","published-online":{"date-parts":[[2022,7,4]]},"reference":[{"key":"erxac77dbbib1","doi-asserted-by":"publisher","first-page":"3","DOI":"10.1007\/978-3-319-40232-1_1","type":"book","article-title":"Rapid growth in the elderly population of the world","volume":"1","author":"Pol","year":"2017"},{"key":"erxac77dbbib2","first-page":"871","type":"journal-article","article-title":"The economic impact of infected joint arthroplasty","volume":"18","author":"Sculco","year":"1995","journal-title":"Orthopedics"},{"key":"erxac77dbbib3","doi-asserted-by":"publisher","first-page":"4845","DOI":"10.1016\/j.biomaterials.2007.07.013","type":"journal-article","article-title":"PEEK biomaterials in trauma, orthopedic and spinal implants","volume":"27","author":"Kurtz","year":"2008","journal-title":"Biomaterials"},{"key":"erxac77dbbib4","doi-asserted-by":"publisher","first-page":"266","DOI":"10.1142\/6562","type":"book","volume":"4","author":"Rakhorst","year":"2008"},{"key":"erxac77dbbib5","doi-asserted-by":"publisher","first-page":"251","DOI":"10.1016\/j.rbo.2016.07.009","type":"journal-article","article-title":"Importance of preclinical evaluation of wear in hip implant designs using simulator machines","volume":"52","author":"Trommer","year":"2017","journal-title":"Rev Bras Ortop"},{"key":"erxac77dbbib6","doi-asserted-by":"publisher","first-page":"113","DOI":"10.17706\/ijmse.2016.4.2.133-125","type":"journal-article","article-title":"Biomaterials in the hip joint replacement","volume":"4","author":"Ghalme","year":"2016","journal-title":"International Journal of Materials Science and Engineering"},{"key":"erxac77dbbib7","doi-asserted-by":"publisher","first-page":"65","DOI":"10.1016\/j.jmbbm.2018.09.021","type":"journal-article","article-title":"Wear and friction of UHMWPE-on-PEEK OPTIMATM","volume":"89","author":"Cowie","year":"2019","journal-title":"J.
