LPBF enables the creation of finely structured, anisotropic microstructures, whose corrosion behaviour is not yet well understood. After production, specimens were heat-treated at 320 \u00b0C, 650 \u00b0C, and in a two-stage treatment at 800 \u00b0C and 400 \u00b0C, followed by hardness and microstructure analysis. Corrosion tests were conducted using linear polarisation, salt spray, and immersion tests. The results show that heat treatments at 320 \u00b0C and 650 \u00b0C have no significant effect on the corrosion rate, while the two-stage treatment shows a slight improvement in corrosion resistance. Differences in microstructure and hardness were observed, with higher treatment temperatures leading to grain growth and tin precipitates. The formation of a passive protective layer was detected after 30 h of OCP measurement. Results from other studies on corrosion behaviour were partially reproducible. Differences could be attributed to varying chemical compositions and manufacturing parameters. These findings contribute to the understanding of the effects of heat treatments on the corrosion resistance of additively manufactured tin bronze and provide important insights for future applications in corrosive environments.<\/jats:p>","DOI":"10.3390\/ma17143525","type":"journal-article","created":{"date-parts":[[2024,7,17]],"date-time":"2024-07-17T12:29:43Z","timestamp":1721219383000},"page":"3525","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Influence of Post-Heat Treatment on Corrosion Behaviour of Additively Manufactured CuSn10 by Laser Powder Bed Fusion"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-5618-0045","authenticated-orcid":false,"given":"Robert","family":"Kremer","sequence":"first","affiliation":[{"name":"Institute of Metallurgy, Clausthal University of Technology, Robert-Koch-Strasse 42, 38678 Clausthal-Zellerfeld, Germany"},{"name":"Faculty of Mechanical Engineering, Dortmund University of Applied Sciences and Arts, Sonnenstr. 96, 44139 Dortmund, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3176-0526","authenticated-orcid":false,"given":"Johannes","family":"Etzkorn","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Dortmund University of Applied Sciences and Arts, Sonnenstr. 96, 44139 Dortmund, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Somayeh","family":"Khani","sequence":"additional","affiliation":[{"name":"Institute of Metallurgy, Clausthal University of Technology, Robert-Koch-Strasse 42, 38678 Clausthal-Zellerfeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamara","family":"Appel","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Dortmund University of Applied Sciences and Arts, Sonnenstr. 96, 44139 Dortmund, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Buhl","sequence":"additional","affiliation":[{"name":"Institute of Metallurgy, Clausthal University of Technology, Robert-Koch-Strasse 42, 38678 Clausthal-Zellerfeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2596-3391","authenticated-orcid":false,"given":"Heinz","family":"Palkowski","sequence":"additional","affiliation":[{"name":"Institute of Metallurgy, Clausthal University of Technology, Robert-Koch-Strasse 42, 38678 Clausthal-Zellerfeld, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"202","DOI":"10.1016\/j.matlet.2015.05.076","article-title":"Additive manufacturing of Cu\u201310Sn bronze","volume":"156","author":"Scudino","year":"2015","journal-title":"Mater.
