Dr. Torbjörn Jonsson is project leader at the division for inorganic environmental chemistry. His research is focused on high temperature corrosion. The aim is to prevent degradation of material at high temperatures. The research is performed by a combination of well controlled exposures and advanced electron microscopy. The research is implemented both on a fundamental level by studies of model systems and in more complex environments as well as in applications. One application is the combustion of biomass which creates a much more corrosive environment in the boiler than combustion of coal and oil. Torbjörn is currently co-supervisor for two PhD students.
