Broadcast in 2020 We have used "iron" since ancient times to build an advanced civilization. Iron is the metal that we humans are most familiar with. However, this metal material has a weakness that could be called its fate: "rust." Iron will inevitably corrode and rust over time. And that "rust" not only makes things look bad, but also weakens structures made of iron. In fact, the mechanism by which this "rust" occurs has not yet been fully elucidated. In addition, the deterioration of buildings due to "rust" is becoming a social problem. Is there a solution to this problem? This time, Galileo X will focus on this "rust" and explore what rust is, and what efforts are currently being made to combat the "rust" that can be said to be the fate of iron.
