what is corrosion?
Corrosion is the gradual deterioration of a metal due to its reaction with substances in the environment, such as air, moisture, acids, or salts.
This process weakens the metal and can damage structures, machines, and everyday objects over time.
Common Examples:
Rusting of iron in the presence of oxygen and water.
Formation of a green coating on copper.
Tarnishing of silver.
Effects of Corrosion:
Reduces the strength of metals.
Causes economic losses due to repair and replacement.
Decreases the lifespan of metal objects.
Prevention Methods:
Painting the metal surface.
Applying oil or grease.
Galvanization (coating iron with zinc).
Electroplating.
In simple terms: Corrosion is the slow damage of metals caused by chemical reactions with the surrounding environment, such as the rusting of iron.
