Lars-Gunnar Johansson

Lars-Gunnar Johansson is a Full Professor in the Department of Chemistry and Chemical Engineering at Chalmers University of Technology. His research focuses on high-temperature corrosion, materials degradation, and the development of corrosion-resistant alloys. He investigates oxidation, nitridation, and chloride-induced corrosion mechanisms in advanced materials, with applications in energy systems and industrial environments.

Key research areas include the behavior of alumina-forming alloys, Mo(Si,Al)₂ composites, and FeCrAl-based materials under extreme conditions. His work employs advanced characterization techniques like neutron reflectivity and in-situ environmental SEM. He also explores protective coatings and surface engineering solutions to mitigate corrosion in biomass-fired boilers, solid oxide fuel cells, and other high-temperature applications.

Publications highlight his contributions to understanding corrosion mechanisms, alloy optimization, and the interplay of environmental factors (e.g., H₂O, KCl, SO₂) on material durability. His research bridges fundamental science with industrial applications, aiming to improve material lifetimes in harsh environments.
