The Role of Oxidation-Reduction in Corrosion Processes

Introduction to Corrosion and its Relevance

The phenomenon of corrosion is not merely a scientific curiosity; it is a critical issue that affects a vast array of sectors, including infrastructure, transportation, and even the safety of our everyday lives. Corrosion can be defined as the gradual degradation of materials, typically metals, due to chemical reactions with their environment. These reactions are often driven by oxidative processes, making an understanding of oxidation-reduction (redox) reactions highly relevant in this context.

Fundamentals of Electrochemical Corrosion

Introduction to Electrochemical Corrosion

Electrochemical corrosion is a complex and significant phenomenon that directly impacts the longevity and usability of various materials, particularly metals. At its core, electrochemical corrosion occurs due to the electrochemical reactions that take place on the surface of a material when it is in contact with an electrolyte, usually in the presence of moisture and oxygen.
