Required Reading

This Module consists of ten Web pages of required reading. The pagination is visible at the bottom of each page with direct links to adjacent pages.

Additional information can be found in sections 5.1 to 5.5 of the reference textbook (Corrosion Engineering: Principles and Practice).


Thermodynamic principles can help explain a corrosion situation in terms of the stability of chemical species and reactions associated with corrosion processes. However, these principles cannot be used to predict corrosion currents or corrosion rates. In reality, the polarization effects control the balancing cathodic and anodic currents that are integrated components of corrosion processes. (reference)

Given the electrochemical nature of corrosion processes it is not surprising to see that measurements and control methods based on electrochemical principles are so extensively used across the whole spectrum of corrosion science and engineering.
