Tokyo Tech scientists have developed a compact α-Al2O3 protective layer for fusion reactors, offering high corrosion resistance and adhesion to metal surfaces. This layer, formed on ODS (oxide dispersion strengthened) FeCrAl alloys, enhances the durability of liquid metal components used in high-temperature environments. The protective layer's structure, enriched with reactive element oxides, promotes layer growth and prevents peeling through a pegging effect. Applications include extending the service life of components in fusion reactors, fast breeder reactors, and solar thermal power plants. This innovation supports the development of sustainable energy technologies.
