Electrochemical Techniques for the Study of Self Healing Coatings

Diverse and complementary methods are required to predict and control the rate of corrosion processes, and also to evaluate the efficiency of corrosion protection methods. Because of the electrochemical nature of the corrosion processes, electrochemical methods are powerful tools to study and evaluate protection methods although their combination with optical and spectroscopic techniques is becoming more prelevant. This chapter describes the conventional electrochemical techniques and the latest advances in local electrochemical methods for the evaluation and characterization of novel protection approaches based on the self-healing concept.
