An overview of the essential aspects of electrochemical corrosion science and engineering that underpin the tools that are available and the technologies that are used for managing corrosion by electrochemical processes and preventing failures.Any process of deterioration (or destruction) and consequent loss of a solid metallic material through an unwanted (or unintentional) chemical or electrochemical attack by its environment starting at its surface is called Corrosion. Thus corrosion is a process ¿reverse of extraction of metals¿. In particular, corrosion can be treated as the spontaneous return of metals to their ores; the large quantities of energy that were consumed in mining, refining, and manufacturing metals into useful objects are rakish by a variety of different itinerary.
