α-Al2O3 Protective Layer That Sticks to Metal Surface with Functions of an Anchor and Peg
Fusion reactors, fast breeder reactors, and solar thermal power plants are being developed as power plants with low environmental impact and no resource constraints. Since these power plants operate at high temperature with large-heat transfer, scientists are studying the use of components that use liquid metal (has excellent heat transfer performance) as a coolant. The liquid metal blanket (a metal wall installed in the core) and the liquid metal divertor (receives heat and discharges exhaust) are among the most important components of fusion reactors and have attracted attention as innovative energy conversion devices. However, the selection of structural materials that are chemically compatible with high-temperature liquid metals has been a challenge.
