Coating, in the context of corrosion, is the thin layers of a covering substance, deposited or applied on a surface of any object, mainly to improve its critical properties and to create a protective barrier against deterioration of the surface due to its reaction with its environment.

When used as a verb, coating is defined as the process of application of covering layers on the surface. The surface on which coating is applied is called as substrate. The coating protects the substrate from deterioration due to electrochemical reaction with the environment. Thus it improves the useful life of structures, pipelines and other vital equipment, and eliminates some of the life threatening failures and costs related to repair and premature replacements.
