Analysis of EIS Data for Common Corrosion Processes

Source

The software program ANALEIS with its modules, BASICS, COATFIT, PITFIT, and ANODAL can be used for the simulation and analysis of EIS data for simple corrosion systems. The advantage of ANALEIS is the optimization of the data analysis for each particular corrosion system based on the characteristics of its equivalent circuit. BASICS is used for systems that are under charge transfer or mass transport control or show an inductive loop. COATFIT addresses the case of the impedance behavior of polymer coated metals. PITFIT can be used to analyze impedance data obtained for localized corrosion of aluminum alloys. Data for anodized and sealed aluminum alloys can be analyzed with ANODAL. Examples are given for the simulation and analysis of impedance data for these corrosion systems.
