Corrosion: The chemical degradation of metals due to reaction with oxygen and moisture.
Explanation
Corrosion is an oxidation process where metals lose electrons and deteriorate. Rusting is the corrosion of iron. Saltwater accelerates corrosion. Corrosion causes significant economic losses and weakens structures. Corrosion prevention methods include painting, galvanizing, and using corrosion-resistant alloys. Noble metals like gold and platinum resist corrosion.
Example
Iron exposed to moisture and oxygen forms rust (iron oxide), which weakens the metal and eventually destroys it.
Frequently Asked Questions
What is the difference between corrosion and rusting?
Corrosion is the general process of metal degradation, while rusting specifically refers to iron corrosion.
How can corrosion be prevented?
Corrosion can be prevented by painting, galvanizing, using stainless steel, or applying protective coatings.
