Quick Answer: Why Is Corrosion A Problem?

Why corrosion is a serious problem?

Aside from the cost in dollars, corrosion is a serious problem because it directly and definitely contributes to the depletion of our natural resources.

For example, steel is made from iron ore and our reserves of iron ore are diminishing..

Why is rusting a problem?

Rust reduces product lifespan If equipment is damaged, more time has to be spent repairing or replacing it, which therefore increases costs. Rust weakens metal by reducing its mass and so after a lot of rusting, the piece of iron may no longer be able to support the weight it once held.

What are the disadvantages of corrosion?

Disadvantages of CorrosionDue to the reaction with oxygen and other elements in the environment, the purity of the metal is hampered.A major part of the top layer of the metal is lost, due to corrosion.It changes the physical appearance of the metal.It changes the chemical composition and the appearance of a metal.More items…•

Why do we need to prevent corrosion?

Corrosion of steel also causes major financial and economic losses. This is because steel and metal are expensive and it is not cost effective to replace them regularly. Also machine breakdown can lead to other losses as well. Corrosion of steel also leads to harmful effects for human health and can cause disease.
