Understanding Corrosion: Electrochemical Principles and Thermodynamics

Corrosion is a silent and costly force that degrades infrastructure, machinery, and everyday materials. To effectively prevent and control this degradation, you must first understand the chemical and energy-driven processes that cause it. This course provides a clear, text-based introduction to the science of corrosion. You will transition from simply recognizing rust to analyzing the exact electrochemical reactions and thermodynamic principles that drive material decay, giving you the foundation to make informed decisions in engineering, maintenance, and material selection. What you'll learn: 1. Learn the foundational terminology of corrosion science and material degradation. 2. Understand the electrochemical cell, including anodes, cathodes, and electron flow. 3. Apply thermodynamic principles, such as Gibbs free energy and the Nernst equation, to predict corrosion reactions. 4. Differentiate between various forms of corrosion, including pitting, galvanic, and erosion-corrosion. 5. Interpret Pourbaix diagrams to determine metal stability in different environments. 6. Explore modern mitigation strategies, including green inhibitors and basic cathodic protection. The course begins with essential chemical definitions and foundational concepts before moving into practical thermodynamic calculations, real-world degradation scenarios, and modern prevention methods. Designed for beginners, this course requires no prior advanced engineering background—only an interest in basic chemistry and material science.
