Corrosion is a process in which the chemical composition of a metal changes when the metal is exposed to external conditions. The physical as well as chemical properties of the metal change as the metal corrodes. The adverse effects of corrosion are as follows:

• Contamination of the product: Corrosion causes contamination of the product.
• Reduced efficiency: Corrosion makes the metal less efficient.
• Damage to metallic equipment: Corrosion damages metallic equipment.
• Damage to commercial airplanes: Corrosion damages commercial airplanes which can cause in-flight problems.
• Damage to oil pipelines: Corrosion damages oil pipelines that can cause ruptures in the pipelines and thus damage the environment.
• Damage to water pipelines: Corrosion damages water pipelines which can lead to leakages and wastage of water.
• Inability to use metallic materials: Corrosion can make metallic materials unusable.
• Loss of valuable materials: Corrosion can lead to the loss of valuable materials such as blockage of pipes, mechanical damage of underground water pipes, and depletion of natural resources.
• Accidents: Corrosion can cause accidents due to mechanical loss of metallic cars, aircraft, bridges, etc. .
• Pollution: Corrosion causes pollution due to escaping products from corrosion.
• Reduced appearance: When appearance is affected, corrosion can reduce the overall value of a building or location.
• Contamination of fluids: Corrosion can contaminate fluids in pipes or vessels.
