Oxidation of Fe-2.25Cr-1Mo in presence of KCl(s) at 400 °C – Crack formation and its influence on oxidation kinetics

Accelerated corrosion of boiler equipment remains a challenge for efficiently utilising biomass- and waste for power production. To overcome this challenge a better understanding of the influence of corrosive species present is required. This study focuses on the influence of KCl(s) on corrosion of Fe-2.25Cr-1Mo at 400 °C. This is done by well-controlled laboratory exposures and detailed microstructural investigation with ion and electron...
