The authors, Bing Yuan, Martin Stephen, and Muni Ramakrishnan from A.W. Chesterton, address the limitations of common EIS data analysis methods and propose a new approach for assessing water/chemical penetration and surface deterioration due to corrosion and erosion. The paper explores the fundamentals of EIS data fitting models, resistors, capacitors, and phase angle differences, providing valuable insights for professionals in materials protection and performance. The first five pages are available for free preview.
