Study Notes
Metal Corrosion
- Primary Cause: Oxidation reaction with the environment is the primary cause of metal corrosion.
-
Prevention Methods:
- Coating: Applying a protective layer to the metal surface (e.g., paint, plating, or coatings)
- Alloying: Modifying the metal's composition by introducing other elements to enhance resistance.
- Cathodic Protection: Using a sacrificial metal or applying an electrical current to create a protective layer.
- Moisture's Role: Moisture acts as an electrolyte, accelerating corrosion by providing a medium for the movement of ions involved in the electrochemical reactions.
- Uniform Corrosion: Uniform corrosion happens when the metal deteriorates evenly across its surface.
- Galvanic Corrosion: Galvanic corrosion occurs when two dissimilar metals are in contact in an electrolyte. The more active metal (the anode) corrodes, while the less active metal (the cathode) is protected.
