Measure Corrosion by Electrochemical Impedance Spectroscopy

Unlock the secrets of corrosion analysis with Electrochemical Impedance Spectroscopy (EIS)! This practical course provides a comprehensive understanding of EIS, a powerful technique for measuring and analyzing corrosion.

We'll start with the fundamentals, demystifying key concepts like impedance, alternating current (AC) signals, and the underlying corrosion surface phenomena. No prior expertise is required – we make EIS accessible to everyone. The course culminates in a hands-on example of fitting complex EIS spectra.

Here's what you'll learn:

• Section 1: Corrosion and Impedance Fundamentals: Build a strong foundation in the principles of corrosion and impedance within electrochemical systems. Understand why and how EIS is applied to corrosion studies.
• Section 2: Surface Processes & EIS Response: Explore how surface processes influence EIS responses. Key topics include polarization resistance, double layer capacitance, and the effect of surface coatings on EIS measurements.
• Section 3: Practical EIS Measurement: Master the practical aspects of acquiring reliable EIS data. Learn about selecting optimal signal amplitude, choosing the appropriate measurement frequency range, and ensuring stationarity for accurate results.
• Section 4: EIS Spectrum Interpretation & Modeling: Decode EIS spectra using equivalent circuit models. Identify characteristic responses and apply fitting techniques to extract valuable insights from your data.

Key takeaways: By the end of this course, you'll be equipped with the knowledge and skills to confidently measure, model, and interpret EIS data for effective corrosion analysis.
