(Bio)- corrosion and conventional protection systems like organic, inorganic and metallic coatings (phosphating, chromatizing and zinc coating) or addition of biocides as sanction against MIC are regulated by EC-directives and some have to be replaced in medium term.
→ Environmental-friendly, biogenic corrosion protection: EPS and EPS-analogues
Microbial biofilms and bacterial extracellular polymeric substances (EPS) can induce and speed up corrosion (microbially influenced corrosion, MIC) or even inhibit corrosion processes (microbially influenced corrosion inhibition, MICI). Both effects are influenced by interactions of the substratum and particularly of the EPS. The chemical composition of EPS decides about the destructive or protective impact and the respective extent.
Scientific findings of former projects:
Aim of this project:
Suppress biofilm formation or blockade selective reactive sites of material by biogenic substances and / or industrial analogues
Application of EPS analogues: Cyclodextrine
(Bio)- corrosion of iron and steels in aqueous media and water-bearing systems
Contribution to the economy
