Corrosion engineering plays a critical role in protecting metal surfaces from deteriorating due to chemical reactions. Understanding the types and mechanisms of corrosion is essential for implementing effective prevention methods.
Definition of corrosion
Corrosion happens when materials, usually metals, are damaged or changed because of a reaction with their environment. This can be rust on your bike after it rains or a green patina on copper roofs.
It’s like the material getting sick from too much exposure to bad stuff around it.
Preventing corrosion is super important because it helps things last longer and saves money. If we ignore corrosion, bridges could weaken, cars might break down faster, and water pipes could leak.
Experts in chemical engineering work hard every day to stop these problems before they start. They use science to protect stuff all over the world from getting ruined by corrosion.
Types of corrosion
Corrosion is a big problem for metals. It can cause them to weaken and break. Here are some common types of corrosion you should know about:
- Uniform Corrosion: This type happens evenly across a metal surface.
- Galvanic Corrosion: Occurs when two different metals touch in a corrosive environment.
- Pitting Corrosion: Causes small holes or pits on the metal, usually hard to see.
- Crevice Corrosion: This type hides in narrow spaces where liquids might get trapped.
- Intergranular Corrosion: Attacks the metal along its grain boundaries.
- Stress Corrosion Cracking: Metal cracks because of stress and corrosion combined.
