Cooling water, corrosion products, sediments, and swabs were analyzed for microstructural, chemical and microbiological characteristics. The cooling water contained sufficient nutrients to support microbial growth, along with chlorides that could compromise material integrity. Chemical analysis of the corrosion products revealed elevated sulfur levels, suggesting microbial activity. Molecular-genetic analysis showed a significant abundance of sulfur-oxidizing, nitrate-reducing, sulfate-reducing, and methylotrophic bacteria in the corrosion products.

Three weld imperfections, namely weld porosity, undercut, and weld ripple, are considered. Two organic coating systems for marine applications are tested. Two weld preparation grades, namely P2 and P3, are included. Stripe coating (yes/no) and inspector level (three inspectors) are additional factors. The samples are exposed to a cyclic accelerated laboratory test according to ISO 12944-9 for varying exposure periods between 1 and 25 weeks. The target parameter is the number of damages in the coatings after exposure. The factor effects are evaluated with a full factorial experimental plan. Results of ANOVA analysis reveal that weld ripple and weld undercut require less thorough preparation (P2), when stripe coating is applied. Weld porosity, in contrast, requires a higher preparation grade (P3). Stripe coating can be omitted for the higher preparation grade. An empirical equation is derived to model the damage progress over exposure time.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 9","pages":"1280-1293"},"PeriodicalIF":2.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144935431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the corrosion of Q235 steel in the marine atmospheric environment starts at the passive film defect, and over time, it gradually develops from pitting corrosion to intergranular corrosion, and then gradually develops from intergranular corrosion to comprehensive corrosion. The whole corrosion process is from point to surface. In addition, a rapid assessment model of the corrosion life of Q235 steel was established by cyclic salt spray accelerated corrosion test. It is verified that the kinetics of the corrosion weight loss of the Q235 steel is in accordance with the power function law, and also observed that Q235 steel surface passivation film as well as passivation film rupture after the generation of dense α-FeOOH rust layer all play a role in resisting corrosion.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 8","pages":"1199-1217"},"PeriodicalIF":2.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144774132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
