Question

What's another word for corrosion?

Answer 1

• Corrosion is a natural process that causes the transformation of pure metals into undesirable substances when they react with substances like water or air.
• This causes damage and disintegration of the metal starting from the portion of the metal exposed to the environment and spreading to the entire bulk of the metal.
• The common form of corrosion is oxidation.
• Another common word for corrosion is rusting. It occurs in iron.
• In the process of rusting, the iron metal reacts with oxygen and moisture present in the air and results in the formation of hydrated Iron (III) oxide or Ferric oxide which is chemically known as rust.
