What is the primary definition of corrosion according to NACE International?

The primary definition of corrosion according to NACE International is the deterioration of a material due to environmental reactions. This concept encompasses the various processes through which metals and other materials degrade when exposed to their surroundings. Corrosion can arise from a combination of factors, such as moisture, oxygen, salts, and other chemicals that may be present in the environment.

Understanding this definition is crucial in the field of corrosion engineering and materials science, as it underscores the importance of monitoring and managing the integrity of materials to prevent loss of functionality and failures. The focus is on the negative impact of environmental interactions on materials, which can lead to structural damage and reduced lifespan of components, necessitating protective measures such as coatings or cathodic protection systems.
