How does the rate of corrosion of iron on the moon compare to that on earth?

I need enough info to write a whole paragraph on it...plz help

Iron corrodes on Earth due to oxidation from atmospheric oxygen. Last time I read, that was not much of concern on the Moon.

There was an important iron corrosion discovery related to the Moon. The Apollo program used N2O4 as a propellant. The stainless steel piping, filters, and metal in the fuel and exhause steams were being corroded by a very complex form of iron nitrate. This was studied extensively, and because this fuel has been since used extensively in many space vehicles (including the Shuttle), adaptations were made which reduced this corrosion.

If you didn't get it, iron does not corrode on the Moon, as the atmosphere which contains oxygen and moisture, does not exist.
