High-Temperature Oxidation of Stainless Steels and SOFC Interconnect Coatings
This community investigates how stainless steels and other alloys degrade in high-temperature oxidizing environments, with a specific focus on developing protective coatings for solid oxide fuel cell interconnects.
The work centers on the oxidation behavior of ferritic and austenitic stainless steels, particularly grades like Crofer 22APU, when exposed to steam, carbon dioxide, or supercritical carbon dioxide. Researchers analyze the formation of oxide scales and the mechanisms of corrosion that lead to electrical resistance increases. A major application area is the development of protective spinel coatings, such as manganese-cobalt oxides, and glass sealants to maintain conductivity and structural integrity in solid oxide fuel cells. The research also examines the role of alloying elements like chromium, nickel, and yttrium in enhancing oxidation resistance and preventing scale spallation.
The largest share of the community's output is found in iron research, accounting for 0.3% of all iron research, and 950 papers here. It also represents 0.9% of chromium research and 0.5% of nickel research.
The community comprises 6,786 papers, publishing most frequently in Oxidation of Metals, Corrosion Science, and the Journal of The Electrochemical Society.
Recent work continues to focus on the corrosion mechanisms of austenitic stainless steels in supercritical carbon dioxide, the long-term oxidation resistance of titanium-based interconnect materials, and the development of glass sealing composites for solid oxide fuel cells.
