Corrosion

Corrosion

The main scope of this group is to address fundamental questions of corrosion science by isolating the crucial problems behind them and designing model experiments for their systematic investigation. A technique of central importance for many research projects within the group is the Scanning Kelvin Probe technique. Based on a world leading expertise in this technique also novel application fields are explored, such as the use of SKP for measuring hydrogen in steels and other alloys. The research in this group comprises very applied as well as very fundamental projects.

Scientific Focus

  • Microscopic and nanoscopic studies of polymer delamination
  • Kinetics of electrochemical reactions at buried interfaces
  • Intelligent self-healing coating systems, conducting polymers
  • Zinc alloy coatings for corrosion protection: performance and galvanizing process
  • Detection of hydrogen in metals with high sensitivity and high spatial resolution: hydrogen uptake, permeation and trapping
  • High-temperature oxidation in short term processes: selective oxidation of alloying elements at surfaces and grain boundaries, e.g. during hot rolling or recrystallization annealing

  • Electrodes in the “dry”: surfaces covered by ultra-thin electrolytes play an important role in many applications and are a key focus of fundamental research within the group

Technological Focus

  • Corrosion protection: intelligent repair and release coatings
  • High-temperature corrosion
  • Hydrogen embrittlement
  • Metallic coatings for cathodic protection
