Corrosion is occurs when a metal becomes wet or damp. A current flows through this, making the unmoving particles throught the steel to the more reactive parts on the surface. These are called anodes. The current returns from the more reactive parts, through it, and then back to the the more still parts. Where the current leaves the anode, rust forms.

Wet corrosion happens when a metal or other material is wet or damp- (or can be caused through the mositure in the air)

Dry corrosion is similar, however the difference is that it forms through the presence of gasses in the air
