Atmospheric corrosion

​Our group has pioneered the systematic investigation of the chemistry and microstructure of atmospheric corrosion, using laboratory exposures under well-controlled conditions and using a large array of methods, including both in-situ and post analysis approaches. We focus on the interplay of humidity and reactive substances in the atmosphere that lead to break-down of the air-formed film on metals and investigate the relation between the microstructure of the material and corrosion. To understand the sequence of events that result in corrosion, we investigate both on the atomic scale, the nanoscale. the microscale and the macroscale. The new knowledge is used to find new approaches for corrosion mitigation. Materials-wise, we presently mainly focus on magnesium and aluminum and their alloys. In addition, we have long experience doing atmospheric corrosion research on other metals (zinc, lead, copper, steel) as well as on natural stones. Atmospheric corrosion research has many application areas, including enhancing the corrosion properties of light-weight alloys (increasing the range of electric cars) and in the conservation of our cultural heritage.
