What is Corrosion?
Corrosion is the deterioration of a metal as a result of chemical reactions between the metal and its environment. Rust is the most common example of corrosion, but the oxidisation of iron is just one example of corrosion. The type of metal and the environmental conditions (particularly gases in contact with the metal) combine to decide the form and speed of deterioration.
The World Corrosion Organisation has estimated the annual global cost of corrosion to be approximately US$ 2.2 trillion, and that up to 25% of this could be avoided by the application of clear and uncomplicated prevention procedures. Utilising existing corrosion control technology could save US$ 660 billion worldwide.
