corrosion

1. galvanic attack: when disimiler metals are placed together.

2. electrochemical corosion: operates in cells like in a car door

3. direct chemical attack: creates a uniform film over the surface

4. electrolytes: solution which allows electrons to flow.

5. reduction: gain of electrons

6. oxididation: loss of electrons

7. corrosion is the chemical detirieration of a matirial.

8. cathode: reduces

9. anode : oxidates
