Biocorrosion of metallic and mineral materials

Biocorrosion of metallic and mineral materials

The attachment of microorganisms onto firm surfaces is a natural, widespread phenomenon, which can be observed at almost every boundary Surface (which is exposed to an aqueous Environment) in the form of biofilms. Biofilms can accelerate the corrosion of Mineral, metallic, and polymeric materials (biocorrosion). It is estimated that annual corrosion damages, calculated as maintenance costs, reach about 6000 Million € in Germany and that 10-20 % of these damages were microbially influenced. To get these mainly biofilm-related Problems under Control, we perform detailed and systematic investigations on the corrosion mechanisms and the involved microorganisms, as well as on the resistance behavior of principally suitable materials (bahavior of microorganisms at Interfaces, biotic-abiotic interactions at Interfaces, material resistance tests).

Our Services
  • Testing on biocorrosion processes of steel and mortar
  • Detection and quantification of microorganisms responsible for corrosion processes
  • Determination of bioactivity of microorganisms by microcalorimetry
  • Design and realization of test plants or use of existing plants for testing corrosion mechanisms as well as for the realization of material testing (corrosion of concrete)
  • Development of measures and support for the prevention and rehabilitation of biocorrosion
