Abstract

Corrosion represents a spontaneous physicochemical transformation in which metals revert to their more stable thermodynamic state, typically oxides, hydroxides, or sulfides, as a result of interaction with environmental elements. Rather than being a simple surface reaction, corrosion is a complex electrochemical phenomenon that significantly influences the durability, reliability, and performance of metallic structures across industrial, marine, and domestic sectors. The consequences extend beyond material degradation, contributing to substantial economic losses, environmental risks, and potential safety failures. The study also highlights the major factors affecting corrosion, including temperature, humidity, pH of the environment, and presence of salts. The effects of corrosion on different metals such as iron, aluminum, copper, zinc, and stainless steel have been examined to understand their behavior in different environments. Various methods of corrosion prevention, including protective coatings, galvanization, electroplating, alloying, cathodic protection, and the use of corrosion inhibitors, have been described. The project also discusses the importance of corrosion studies in industries such as construction, oil and gas, transportation, and marine applications. The study concludes that proper understanding and control of corrosion are essential for increasing the life of metal structures, reducing maintenance costs, and ensuring safety. Corrosion studies play an important role in material science and industrial development by helping in the selection of suitable materials and effective protection methods.
