Current research interests
With an increasing effort to acquire renewable energy sources, an effort is being made to fuel powerplants with biomass instead of coal. The change of the fuel source, however, presents new challenges to the materials used in the powerplants. Since biofuel contains a significantly larger amount of H2O and Cl2 than coal does, different chemical reactions take place, rendering the usually protective Fe-Cr steels ineffective. This causes major degradation of the steel, making frequent replacements necessary.
The goal of my project is to understand the fundamentals of this hot temperature corrosion in wet and/or chloride bearing atmospheres.
Information gained through SEM, XRD and Synchrotron radiation will be used to develop a corrosion model, describing the growth kinetics of the resulting corrosion layers and how the initial chemical composition influences the corrosion.
