Corrosion

Chapter Objectives

  1. Define corrosion and the corresponding electrochemical reactions often associated with it.
  2. Be able to rate the reactivity (cathodic versus anodic) of some important pure metals based on standard half-cell potentials.
  3. Define a galvanic cell, its important elements, the role of electrolyte in it, and various circumstances under which a galvanic cell is created in real life.
  4. Explain the basic aspects of corrosion kinetics and define polarization, passivation, and the galvanic series.
  5. Define various types of corrosion and the circumstances under which each occurs in everyday life.
  6. Define oxidation and how it can protect metals.
  7. Name various ways that one can protect against corrosion.
