As the results of immersion and electrochemical tests showed, both alloys had a faster corrosion rate in the fusion zone than in the base metal. Laser welding caused interdendritic segregation, and spread the intermetallic compounds (IMCs) evenly throughout in the fusion zone. This increased the micro-galvanic corrosion sites and destabilized the passive film, thus increasing the corrosion rate of the fusion zone. However, Zr in the Al\u2013Mn alloy reduced the size and number of IMCs, and minimized the micro-galvanic corrosion effect. Consequently, Al\u2013Mn\u2013Zr alloy has higher corrosion resistance than AA3003 even after laser welding.<\/jats:p>","DOI":"10.3390\/ma16176009","type":"journal-article","created":{"date-parts":[[2023,9,1]],"date-time":"2023-09-01T09:12:22Z","timestamp":1693559542000},"page":"6009","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Microstructure and Corrosion Behavior of Laser-Welded Al\u2013Mn\u2013Zr Alloy for Heat Exchanger"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9275-6662","authenticated-orcid":false,"given":"Jeong-Min","family":"Lim","sequence":"first","affiliation":[{"name":"School of Advanced Materials Science and Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-Gu, Suwon-si 16419, Gyeonggi-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoon-Sik","family":"So","sequence":"additional","affiliation":[{"name":"School of Advanced Materials Science and Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-Gu, Suwon-si 16419, Gyeonggi-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung-Gu","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Advanced Materials Science and Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-Gu, Suwon-si 16419, Gyeonggi-do, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"667","DOI":"10.1016\/j.ijheatmasstransfer.2016.05.032","article-title":"Enhancement of heat transfer in a fin-tube heat exchanger using rectangular winglet type vortex generators","volume":"101","author":"Sinha","year":"2016","journal-title":"Int.
