Preventing Corrosion: Understanding Rusting and Methods for Protection

The video tutorial explains corrosion, focusing on rusting, a chemical reaction involving iron, oxygen, and water. It contrasts this with aluminium oxidation, where aluminium forms a protective oxide layer. An experiment with test tubes demonstrates that both water and oxygen are necessary for rusting. The video concludes with methods to prevent corrosion, such as barrier methods and sacrificial protection, including galvanization.
