17.1 Corrosion and Its Adverse Impact

Corrosion is the material’s destructive reaction to its surrounding environment. During the past years, it has caused irreparable damage to human life [1]. Corrosion costs manifest in the form of premature deterioration or failure necessitating maintenance, repairs, and replacement of damaged parts. Corrosion has a vast environmental and economic impact on all the surfaces of national infrastructure like highways, bridges, buildings, chemical processing units, wastewater treatment, and virtually on all metallic objects in our day-to-day life use [2]. Other than material loss, corrosion interferes not only with the environment but also affects human safety and industrial operations severely. Awareness of corrosion and adaptation of timely and appropriate control measures hold the key to the abatement of corrosion failures.

The use of corrosion inhibitors [3, 4], cathodic protection [5, 6], different types of coatings on the surface [7], alloying elements, and additives [8] are several methods for controlling corrosion.
