Abstract

Electrochemical impedance spectroscopy (EIS) methods are commonly used to estimate the performance of corrosion resistant coatings. A multi-frequency EIS improves performance over traditional EIS systems through shortened trial times. With the addition of real-time performance monitors, a multi-frequency EIS system provides users with a better understanding of estimate quality and automatically adjusts a variety of parameters to further improve instrument performance. Such an automated multi-frequency EIS system is realized with modern digital signal processing (DSP) hard-ware
