# CORROSION :--- The loss of materials ( metals and alloys ) or its useful properties by chemical and electrochemical interactions with its environment is called corrosion.
# DRY CORROSION :--- Dry Corrosion occurs when there is no water and moisture to aid the corrosion , and the metal oxidises with the atmosphere alone.
# WET CORROSION :---- Wet Corrosion of metals occurs through electron transfer , involving two processes oxidation and reduction.
In oxidation metal atoms loose electrons , the surrounding environment then gains the electrons in reduction.
