Biogenic Sulfuric Acid Corrosion BSA

The number of damages caused by biogenic sulfuric acid corrosion (BSA) is increasing. The development of materials resistant to BSA requires testing methods that allow for a testing of the materials that is both oriented towards practice and accelerated. To achieve this, test rigs were setup at Fraunhofer UMSICHT. In cooperation with the University of Duisburg-Essen (Dept. of Chemistry, Biofilm Centre, Prof. Dr. Wolfgang Sand), weathering tests were conducted to assess the BSA resistance of materials. The results provided indications for a targeted optimization and further development of the materials.
