    Abstract

    The software program BASICS can be used for the simulation and analysis of simple corrosion systems which are under charge transfer or mass transport control. Data for systems under charge transfer control ( one-time-constant model ) can be analyzed with the Bodefit method using Bode-plots, the Cirflt method using complex plane plots, and the Intfit method using plots of —Z″ versus log f. Data for systems under mass transport control can be analyzed with the Warfit method using complex plane or Randles-plots. Systems for which an inductive loop is observed can be analyzed with the Indflt method. Examples are given for the simulation and analysis of impedance data for the three different systems.
