Researchers explored protective coatings to resist corrosion in fusion reactors. They tested -Al2O3 oxide layers on ODS alloys in a high-temperature, flowing lithium-lead environment. Even bare ODS alloys formed a durable -LiAlO2 layer in situ, which suppressed further corrosion. The layers exhibited strong adhesion under mechanical stress, making these findings crucial for improving material durability in fusion reactors and high-temperature energy systems.
