Study Notes
Corrosion of Metals
- Metals have a natural tendency to return to their natural state, which can lead to degradation when used in various forms.
Corrosion Process
- Corrosion is the process where a solid metallic material is destroyed through an unwanted chemical or electrochemical attack by its environment.
Types of Corrosion
- Dry corrosion occurs when the attack of air or oxygen on the metal forms an oxide layer over the surface.
Rust Formation
- When iron is exposed to atmospheric conditions, it forms rust (iron oxide).
Corrosion vs. Extraction
- The extraction of metals from their ores is considered the opposite of corrosion, as it involves the removal of impurities to obtain pure metal.
