This book presents the key concepts in  electrochemistry applied to metal corrosion, such as processes at the metal-medium boundary and the role of electrochemical cells in redox reactions. It covers thermodynamic principles, including Gibbs energy, the Nernst equation, Pourbaix diagrams, and polarization curves, essential for predicting electrode reactions. The chapters classifies corrosion types like electrochemical, pitting, crevice, and intergranular, with a focus on mechano-chemical corrosion in welded structures. Visual diagrams simplify complex concepts, while real-world...
