$\huge{\red{\mathfrak{ANSWER:-}}}$

Corrosion is the deterioration of a metal as a result of chemical reactions between it and the surrounding environment. Both the type of metal and the environmental conditions, particularly gasses that are in contact with the metal, determine the form and rate of deterioration.

Answer 2

Answer:

Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide. It is the gradual destruction of materials (usually metals) by chemical and/or electrochemical reaction with their environment.

Corrosion Causes and Prevention. Obviously, the most common type of corrosion is the formation of rust, or Iron Oxide, on the surface of metals containing iron when they come into contact with Oxygen.
