The variety of conditions in which corrosion appears and its various forms makes corrosion analysis a complex process. Because of the variety of corrosion forms and conditions, there is no universal corrosion test for all situations.

For the precious metal wires, the range of industrial applications is wide and varied.

Cast iron is known for quickly disintegrating if not kept in a wet environment after excavation from the sea. This iron can be corroded by graphitization which leaves behind a metal core but has an outer shell of graphite that contains iron corrosion products.

• Protective coating method
• Desiccant method
• VCI (Volatile Corrosion Inhibitor) method

Microbes/microorganisms can sometimes induce the corrosion of steel and non-ferrous metals or they can accelerate normal electro-chemical corrosion processes.

Microbially influenced corrosion (MIC) can be defined as accelerated corrosion of susceptible metals as a result of the direct, indirect, or combined actions of microbial metabolism.
