Nevertheless, if the laser parameters are not properly optimised, this process may unintentionally provoke corrosion. Maintaining the structural integrity of these materials is essential for ensuring patient safety and minimising long-term costs. This work aims to optimise the laser scanning parameters for marking 316L stainless steel (316L SS), seeking to improve its corrosion resistance. The corrosion behaviour was assessed by using open circuit potential (OCP), potentiodynamic polarisation curves (PPc), and electrochemical impedance spectroscopy (EIS) techniques, conducted in 0.9% wt NaCl solution at a controlled temperature of 25 \u00b1 1 \u00b0C. A comprehensive study employing optical profilometry has significantly enhanced our understanding of the corrosion micromechanisms of 316L SS, comparing specimens both with and without NsPFL treatment. Considering applications involving environments rich in chloride ions, the results indicated that the NsPFL-316L SS samples demonstrated markedly enhanced performance compared to the untreated base material after 48 h of immersion in 0.9% wt NaCl solution. This improvement is particularly noteworthy given the widespread utilisation of 316L SS in the manufacturing of surgical instruments, where corrosion resistance is of paramount importance.<\/jats:p>","DOI":"10.3390\/ma17246178","type":"journal-article","created":{"date-parts":[[2024,12,18]],"date-time":"2024-12-18T03:40:56Z","timestamp":1734493256000},"page":"6178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Use of Nanosecond Pulsed Fibre Laser Treatment to Improve the Corrosion Resistance of 316L SS Utilised as Surgical Devices"],"prefix":"10.3390","volume":"17","author":[{"given":"Vinicius da Silva","family":"Neves","sequence":"first","affiliation":[{"name":"Materials Engineering Department, S\u00e3o Carlos School of Engineering (EESC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13563-120, SP, Brazil"},{"name":"S\u00e3o Carlos Institute of Physics (IFSC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13566-590, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felipe Queiroz","family":"Correa","sequence":"additional","affiliation":[{"name":"Materials Engineering Department, S\u00e3o Carlos School of Engineering (EESC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13563-120, SP, Brazil"},{"name":"S\u00e3o Carlos Institute of Physics (IFSC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13566-590, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1694-3583","authenticated-orcid":false,"given":"Murilo Oliveira Alves","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Materials Engineering Department, S\u00e3o Carlos School of Engineering (EESC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13563-120, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3536-0885","authenticated-orcid":false,"given":"Alessandro Roger","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, S\u00e3o Carlos School of Engineering (EESC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13566-590, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8919-140X","authenticated-orcid":false,"given":"Witor","family":"Wolf","sequence":"additional","affiliation":[{"name":"Materials Engineering Department, S\u00e3o Carlos School of Engineering (EESC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13563-120, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9195-7689","authenticated-orcid":false,"given":"Rodrigo","family":"Galo","sequence":"additional","affiliation":[{"name":"School of Dentistry of Ribeir\u00e3o Preto, University of S\u00e3o Paulo (USP), Ribeir\u00e3o Preto 14040-904, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1192-3073","authenticated-orcid":false,"given":"F\u00e1tima Maria Mitsue","family":"Yasuoka","sequence":"additional","affiliation":[{"name":"S\u00e3o Carlos Institute of Physics (IFSC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13566-590, SP, Brazil"},{"name":"BR Labs Tecnologia \u00d3ptica e Fot\u00f4nica Ltd., S\u00e3o Carlos 13567-020, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9837-3216","authenticated-orcid":false,"given":"J\u00e9ferson Aparecido","family":"Moreto","sequence":"additional","affiliation":[{"name":"Materials Engineering Department, S\u00e3o Carlos School of Engineering (EESC), University of S\u00e3o Paulo (USP), S\u00e3o Carlos 13563-120, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,18]]},"reference":[{"key":"ref_1","first-page":"81","article-title":"316L stainless steel mechanical and tribological behavior\u2014A comparison between selective laser melting, hot pressing and conventional casting","volume":"16","author":"Bartolomeu","year":"2017","journal-title":"Addit.
