Team up Experimental And Modeling Work on Oxidation Reaction Kinetics

Purpose and goal

The overall goal of the project has been to develop models that can be used for quantitative simulations of high-temperature corrosion. This has been achieved through combining well-controlled corrosion experiments, high-resolution microscopy and microanalysis with thermodynamic and kinetic modelling. Models has successfully been developed to simulate oxidation of iron, chromium and aluminum at high temperatures and a first attempt to model the secondary protection has been performed.

Expected results and effects

The development of the simulation models themselves as well as the development of software open opportunities for materials design, life-time assessments and material selection. To accelerate the development of high temperature steels as well as improve material selection for the applications represented by the project partners, modelling will be an important aspect. The project result is a first step in implementing modelling of high-temperature corrosion.

Planned approach and implementation

The research strategy has been to combine well-controlled corrosion experiments, high-resolution microscopy and microanalysis with thermodynamic and kinetic modelling. A key component in the project set-up has been partners active in different research fields (modelling and high-temperature corrosion). This setup together with companies covering the whole value chain has proven to be very fruitful to develop the models and interpret the results.
