Does corrosion require oxygen and water?

I know rusting (a form of corrosion) requires H2O and O2

 

but corrosion in general is just an oxidation-reduction reaction, right?

Edited by DivideByZero

it all depends on what's being corroded. wax can be corroded by oils. paper can be corroded by water. It's just breaking down.

 

Oxygen and water are both common corrosive agents because they are very common materials and also quite reactive. Other less common reagents are more corrosive but we dont see them every day. Examples are chlorine gas, acids, bases, titanium tetrachloride, etc etc etc

So can a reaction of a metal (Zinc) with an acid (HCl) be classified as corrosion where the Zn looses mass?
