Learn the Fundamentals of Corrosion Electrochemistry

Master Corrosion Electrochemistry: A Comprehensive Online Course

Deepen your understanding of aqueous corrosion with this in-depth online course focusing on the electrochemical aspects of corrosion. This course provides a strong foundation in corrosion-related processes from an electrochemical perspective, covering fundamental principles to practical measurement techniques.

Course Sections:

• Electrochemical Nature of Aqueous Corrosion: Explore the fundamental principles and classifications of corrosion. Understand anodic and cathodic reactions, the movement of electrical charge in metals and electrolytes, and apply Faraday's law to corrosion calculations.

• Corrosion Thermodynamics: Delve into the thermodynamic aspects of corrosion. Learn the significance of potential measurements, standard potentials, and the Nernst equation. Interpret Pourbaix diagrams to assess the thermodynamic feasibility of reactions based on pH and potential, understanding how thermodynamics governs corrosion behavior for various metal/environment combinations.

• Kinetics of Corrosion Reactions: Focus on the kinetics of corrosion processes. Study key concepts like activation-controlled reactions and diffusion-limited reactions. Learn about factors influencing cathodic reactions (oxygen reduction, hydrogen evolution) and the formation of protective oxide films.

• Corrosion Behaviors: Master the use of Evans diagrams for analyzing corroding electrodes with multiple reactions and estimate corrosion currents using the Stern-Geary equation. Gain the ability to interpret potentiodynamic polarization curves to assess corrosion mechanisms and analyze the behavior of passive metals in corrosive environments.

• Electrochemical Measurements: Learn practical techniques for conducting electrochemical measurements. This includes setting up a three-electrode cell, converting potential measurements to the hydrogen reference electrode standard, and understanding potential limits referenced to the open circuit potential and reference electrode. Understand and manipulate key parameters for potentiodynamic polarization and linear polarization experiments, and recognize the impact of electrolyte resistance on polarization curves.

By the end of this course, you will be able to:

• Analyze, evaluate, and experimentally measure corrosion processes using linear polarisation and potentiodynamic polarization methods.
• Apply electrochemical principles to understand and predict corrosion behavior.

Important Note: This course focuses specifically on corrosion electrochemistry. It has some overlap with the 'Introduction to Corrosion Science and Engineering' course. If you seek a broader overview of corrosion mechanisms, protection measures, and minimal electrochemistry theory, the 'Introduction to Corrosion Science and Engineering' course is recommended.
