Preface

Although it is frequently silent and subtle, corrosion is perhaps the most important factor contributing to the decline of social systems. One of the most important technological challenges facing our country and the rest of the globe is extending the life of structures and engineered materials while maintaining public safety and the environment. A wide range of materials and systems are affected by corrosion-related issues, which have an impact on our daily life. Numerous economic sectors in the country are severely impacted by corrosion. Corrosion costs billions of dollars every year in lost revenue. By utilizing already accessible corrosion management technology, the annual cost of corrosion can be cut to 20 to 25 percent of that amount. Materials selection, correct design, electrochemical protective coating, and inhibitors are common corrosion

We are subjected to many types of corrosion or degradation daily. Corrosion is a risky and very expensive issue. It can cause bridges and buildings to fall, oil pipelines and chemical factories to leak, and restrooms to flood. Corroded medical implants may result in blood poisoning, corroded electrical contacts can result in fires and other issues, and air pollution has resulted in corrosion damage to works of art all over the world. Corrosion is an interdisciplinary subject and is a burning topic for researchers all over the world. It is equally related to chemistry, chemical engineering, mechanical engineering, aviation, metallurgy, materials science, petroleum, refineries, and many

Electrochemical processes are the main causes of the most prevalent types of corrosion. General corrosion happens when the majority of or all the atoms on a metal surface are oxidized, causing the surface to corrode completely. Most metals are easily oxidized, which means they frequently lose electrons to oxygen (among other elements) in the air or in water. Oxygen joins with the metal to produce an oxide as it is reduced (gains electrons). Corrosion is a sort of redox reaction where oxidation and reduction take

The existing corrosion protection technologies are unable to stop corrosion. However, they can mitigate corrosion to some extent. Utilizing inhibitors, coatings, and other corrosion prevention techniques to solve this issue is a successful strategy. Furthermore, the creation of biodegradable and environmentally friendly inhibitors is becoming a crucial issue as regulations for the use of inhibitors get stricter and more demanding in terms of the ecological aspect. To prevent the corrosion of metals and alloys, a variety of techniques are used, including those that utilize polymers, nanocomposites, biopoly-
