what is corrosion.. 3
Answers
Corrosion is the process of decay on a material caused by a chemical reaction with its environment. The reaction is typically in the form of oxidation. Corrosion of metal occurs when an exposed surface comes in contact with a gas or liquid, and the process is accelerated by exposure to warm temperatures, acids, and salts. Most metals are susceptible to corrosion, but all materials are subject to degradation. For example, corrosion of the polymers used to insulate coatings on electrical wiring has been a concern in older airplanes.
Carbon steel is the most widely used material for engineering applications, consisting of about 85% of all steel production each year. Even though carbon steel is susceptible to corrosion, it’s used in everything from nuclear power and fossil fuel power plants to oil and gas refining and pipelines.

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 engineering is the field dedicated to controlling and stopping corrosion.
