Coating refers to the application of a layer of material onto a surface to protect it from environmental factors that can cause degradation, such as corrosion. In the context of corrosion, coatings serve as barriers that prevent moisture, oxygen, and other corrosive agents from reaching the substrate, thereby extending the lifespan of materials like metals and alloys. The effectiveness of a coating can greatly influence the overall durability and performance of structures exposed to corrosive environments.
