- Measurement, Modeling, Data Interpretation and Applications
Course Objectives
Created in July 1995 last updated 20 May 2003
To understand the fundamentals of electrochemical impedance spectroscopy and to gain hands on experience in impedance measurements, equivalent circuit modeling, data interpretation and practical applications of this powerful technique in evaluation, testing/monitoring and life-prediction of anodized, coated and painted structures/components.
This course thoroughly and systematically covers the fundamentals of electrochemical impedance spectroscopy, the procedures/steps involved in EIS measurements, equivalent circuit modeling, data interpretation and practical applications in corrosion testing and monitoring. Participants of this course will gain hands on experience in operating the state-of-the-art EIS equipment to collect impedance data. The participants will also gain hands on experience in using EIS modelling softwares such as ZView and Boukamp's Equivcrt. The detailed procedures for equivalent circuit modeling using both ZView and Boukamp's Equivcrt software will be a major part of this training course. The following topics will be covered:
1. Fundamental concepts in electrochemistry
