This study employs techniques such as XRD, OM, SEM, EBSD, and electrochemical testing to analyze the microstructure, crystal structure, chemical composition, and corrosion performance of bronze earrings unearthed at the Xindianzi site in Inner Mongolia. The results indicate the presence of work-hardened structures, including twinning and equiaxed crystals, on the earrings\u2019 surface. With an increase in chloride ion concentration in NaCl solutions from 10\u22123 mol\/L to 1 mol\/L, the corrosion current density of the bronze earrings increased from 2.372 \u00d7 10\u22127 A\/cm2 to 9.051 \u00d7 10\u22127 A\/cm2, demonstrating that the alloy\u2019s corrosion rate escalates with chloride ion concentration. A 3-day immersion test in 0.5% NaCl solution showed the formation of a passivation layer of metal oxides on the earrings\u2019 surface. These findings underscore the significance of the impact chloride ions have on the corrosion of copper alloys, suggesting that activating the alloy\u2019s reactive responses can accelerate the corrosion process and provide essential insights into the corrosion mechanisms of bronze artifacts in chloride-containing environments.<\/jats:p>","DOI":"10.3390\/ma17081734","type":"journal-article","created":{"date-parts":[[2024,4,10]],"date-time":"2024-04-10T10:55:28Z","timestamp":1712746528000},"page":"1734","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Microstructure and Chlorine Ion Corrosion Performance in Bronze Earring Relics"],"prefix":"10.3390","volume":"17","author":[{"given":"Zhiqiang","family":"Song","sequence":"first","affiliation":[{"name":"Institute for the History of Science and Technology, Inner Mongolia Normal University, 81 Zhaowuda Road, Hohhot 010022, China"},{"name":"College of Physics and Electronic Information, Inner Mongolia Normal University, 81 Zhaowuda Road, Hohhot 010022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ojiyed","family":"Tegus","sequence":"additional","affiliation":[{"name":"Institute for the History of Science and Technology, Inner Mongolia Normal University, 81 Zhaowuda Road, Hohhot 010022, China"},{"name":"College of Physics and Electronic Information, Inner Mongolia Normal University, 81 Zhaowuda Road, Hohhot 010022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1328","DOI":"10.1002\/mawe.202100076","article-title":"Thermodynamic analysis of nanocrystalline solid solutions formation in copper-lead-tin ternary immiscible system during mechanical alloying","volume":"52","author":"Wu","year":"2021","journal-title":"Mater.
