CORROSION:
Corrosion is the deterioration of materials as a result of reaction with its environment
Or we can also say that, Corrosion is the destructive attack of a metal by CHEMICAL or ELECTROCHEMICAL reaction with the environment.
Examples:
• Rust on iron 
• Blue-Green color on Copper
• Tarnish on Silver

Factor influencing Corrosion:

◉ Position of Metals in Electrochemical Series
◉ Presence of Electrolytes
◉ Impurities in Metals
◉ Difference of Temperature
◉ Concentration of Oxygen

Corrosive Environment:

• Water (Fresh, Distilled, Rain or Salt)
• Steam and Gas (H2S, NH3, Cl, SO2, NOx)
• Air and Humidity
• Atmosphere (Rural, Industrial, Marine, Urban)
• Chemicals (Acids, Alkalies)
• Soils
