However, exposure to algae is inevitable when a metal is used in marine environments. Hence, the effect of algae on corrosion is potentially a critical issue, particularly for Mg alloys that are generally very susceptible to corrosion. In this paper, the biofouling and corrosion of magnesium (Mg) alloys WE43 and AM60 caused by <em>Chlorella vulgaris</em> (<em>C. vulgaris</em>), a typical marine microalga, were systematically investigated. The fluorescence images and sessile cell counting results proved that the antibacterial mechanism of the Mg alloys in medical field was not applicable in marine environments. <em>C. vulgaris</em> could adhere to the surfaces of WE43 and AM60, leading to the occurrence of biofouling and biocorrosion. Moreover, <em>C. vulgaris</em> tended to damage the surface film of the WE43 alloy more severely than that of the AM60 alloy, resulting in larger and deeper pits on the surface of the WE43 alloy. Liquid chromatography-mass spectrometry (LC-MS/MS) tests and etidronic acid (HEDP) addition experiments confirmed that the organic acids produced by <em>C. vulgaris</em> through photosynthesis were the main culprits for the dissolution or failure of the surface film. Meanwhile, the inorganic substance (NH<sub>4</sub>)H<sub>2</sub>PO<sub>4</sub> produced by <em>C. vulgaris</em> through respiration and high concentration of Cl<sup>−</sup> could also promote the rupture of the surface film and aggravate the corrosion damage of Mg alloys. The mechanisms of the <em>C. vulgaris</em> induced corrosion and biofouling are proposed at last based on the experimental measurements in this paper.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"250 ","pages":"Article 112884"},"PeriodicalIF":7.4,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
