Question

Why is the prevention of corrosion important?

Solution

Corrosion

  • Corrosion is a natural process that converts a refined metal to a more chemically stable state, such as oxide, hydroxide, or sulfide, thus damaging the surface of metal.
  • For example, when iron rusts, it loses its toughness, and the rusty iron crumbles readily.

Importance of prevention of corrosion

  • Corrosion can cause metal purity to deteriorate.
  • Corrosion may also cause the loss of several critical metal characteristics.
  • When a metal structure corrodes, it loses strength, and the risk of structural collapse increases.
  • Corrosive attacks on metal can significantly raise the cost of structural maintenance if corrosion prevention measures are not used.
  • Corrosion can also be harmful to humans.
  • An example would be rusty iron cuts that puncture the skin and cause tetanus.
  • Thus, prevention of corrosion is much needed and very important.
