What is Corrosion? Do we observe corrosion only in Iron?
Asked by Topperlearning User | 25 Jun, 2014, 09:50: AM
answered-by-expert Expert Answer

The corrosion process is a slow, natural and normal occurring electrochemical reaction that takes place when metal objects are exposed to an oxidizing environment usually under wet or moist conditions. In this process metal surface slowly reacts with components of air forming undesirable substances on its surface. No, we observe corrosion in other metals also.
