TY - GEN A1 - Babutzka, Martin A1 - et al., T1 - Exposure Site Catalogue - Catalogue of atmospheric corrosion field exposure sites in Europe N2 - Exposure sites and outdoor exposure have always been a part of atmospheric corrosion research providing the “final answer”, although at the cost of long exposure times. Individual exposure programs such as ISOCORRAG, MICAT and ICP Materials have resulted in collaborative networks of exposure sites. So far, however, there has been no collective effort to put together currently active sites in a comprehensive manner and across programs and nations. The information collected in the catalogue is possible thanks to the work of all individual site managers listed as contact persons, efforts of members of Working Party 25 (WP25) Atmospheric Corrosion of the European Federation of Corrosion (EFC) and financial support of the EFC. With this Catalogue you can both get a general overview of what is available and be guided if you are looking for a particular environment with certain characteristics.

For applications indoor it is possible to produce decor glass by using enamel colors and glass painting techniques without any problems. However, this is more limited for applications outdoor. Humidity and environmental pollution attack the surface of the coating and damage it strongly. There are only few colors on the market which are resistant towards acids and bases until now. Additionally, most of those colors are opaque. In order to extend the color palette, chemically resistant colored glasses are being developed which are transparent, relatively low melting and intensively toned even in thin coat thickness. To achieve such ambitious aim, many parameters have to match which act in complex manner. Metal oxides were used to color the glasses. A lead-free glass composition was developed to avoid an exposition of heavy metals to the environment. The glasses were characterized, in particular in terms of their thermal properties, their crystallization and corrosion behavior as well as their chemical and environmental durability. Different practical applications will be shown.

The network is called "die junge gfkorr" and has the following aims: (i) Initiation of in-person events with excursions and a networking atmosphere. (ii) Members come from both industry and academia can find similarities in each other's work (iii) Get to know each other and learn from each other, and (iv) Members benefit long-term by using the network throughout their careers and for future collaboration on daily business and research projects.

Unlike the USA, Canada, and Australia, Europe has less developed cooperation on MIC. Although several research groups and industrial stakeholders are addressing MIC, discussions remain fragmented, and information exchange is limited. A truly transdisciplinary approach is rarely seen. As a result, Europe often relies on methods, preventive measures, and standards from other regions, as there are no equivalent European standards. This situation makes Europe a) highly dependent, and b) in some cases, unable to use certain measures or standards due to European legal restrictions (e.g., the use of biocides). In 2021, researchers established the “Euro-MIC” network, financially supported by the EU project “COST-Action,” to tackle these issues. Through COST-Action, Euro-MIC aims to facilitate necessary interactions, communication, knowledge sharing, and training for personnel and researchers across various disciplines. COST-Action supports network activities, workshops, training schools, conferences, and more. Euro-MIC aspires to position Europe as a leader in MIC, promoting ideas on par with other nations while upholding European values and ensuring greater protection for people, property, and the environment. In this presentation, I will briefly introduce the principles of COST Action and highlight the significant opportunities provided by this EU-funded project. COST Action fosters interdisciplinarity, networking, training, scientific exchange, and the promotion of young scientists. By showcasing some examples of CA20130 COST ACTION Euro-MIC, I hope to demonstrate that COST Action is not only relevant for addressing MIC but can also be applied to other important topics and sectors.

T1 - Microbiologically Influenced Corrosion (MIC) by Halophilic (Salt-Loving) Nitrate and Sulfate-Reducing Microorganisms N2 - The survey of Canadian shale sites showed a dominance of halophilic microorganisms, including Halomonas (HA). Nitrate-amended incubations of the field samples under high salinity (14.6% NaCl), revealed a dominance of HA (>72%) and an accumulation of nitrite. Nitrite accumulation directly inhibited the growth of SRB, thereby decreasing their souring and corrosion risks. However, accumulated nitrite may also contribute to iron corrosion, which will be tested by using different concentrations of nitrate as an electron acceptor to HA. Different salinities are further tested on HA strains supplemented with iron coupons to determine their effects on iron corrosion rates. HA incubated with separate cultures of corrosive methanogen and SRB were tested to determine whether a positive or adverse effect will occur between them. Lastly, analyses of iron coupons will be conducted using TOF-SIMS, FIB-SEM and EDS for corrosion product characterization T2 - Corrosion 2021 CY - Online Meeting DA - 19.04.2021 KW - MIC KW - Bacteria KW - Halophile KW - Corrosion KW - Environmental condition KW - Korrosion KW - High salinity PY - 2021 UR - https://my.nace.org/PaperTrail/Authors/Submission.aspx?id=2914f145-7f8f-ea11-813a-005056a95a7c SP - Paper C2021-16284, 1 AN - OPUS4-52479 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER - TY - JOUR A1 - Koerdt, Andrea A1 - Gerengi, Husnu A1 - Kaya, Ertugrul A1 - M. Solomon, Moses A1 - Snape, Matthew T1 - Advances in the Mitigation of Microbiologically Influenced Concrete Corrosion: A Snapshot N2 - Concrete, a versatile construction material, faces pervasive deterioration due to microbiologically influenced corrosion (MIC) in various applications, including sewer systems, marine engineering, and buildings. MIC is initiated by microbial activities such as involving sulfate-reducing bacteria (SRB), sulfur-oxidizing bacteria (SOB), etc., producing corrosive substances like sulfuric acid. This process significantly impacts structures, causing economic losses and environmental concerns. Despite over a century of research, MIC remains a debated issue, lacking standardized assessment methods. Microorganisms contribute to concrete degradation through physical and chemical means. In the oil and gas industry, SRB and SOB activities may adversely affect concrete in offshore platforms. MIC challenges also arise in cooling water systems and civil infrastructures, impacting concrete surfaces. Sewer systems experience biogenic corrosion, primarily driven by SRB activities, leading to concrete deterioration. Mitigation traditionally involves the use of biocides and surface coatings, but their long-term effectiveness and environmental impact are questionable. Nowadays, it is important to design more eco-friendly mitigation products. The microbial-influenced carbonate precipitation is one of the green techniques and involves incorporating beneficial bacteria with antibacterial activity into cementitious materials to prevent the growth and the formation of a community that contains species that are pathogenic or may be responsible for MIC. These innovative strategies present promising avenues for addressing MIC challenges and preserving the integrity of concrete structures. This review provides a snapshot of the MIC in various areas and mitigation measures, excluding underlying mechanisms and broader influencing factors.

Methanogenetic Archaea are also known to be involved in iron corrosion, forming a multi-species biofilm on corroding metallic structures. However, mechanistic details and kinetics of the overall process in methanogen-induced MIC are poorly understood.
