Abstract: One area in which computers find use is in the calculation of Corrosion current density and rate calculations. To calculate electrochemical parameters such as anodic and cathodic Tafel slopes, corrosion current density and polarisation resistance, a software has been developed using C++ language. The software would process data obtained either from a galvanostatic experiment or potentiostatic experiment. The potentials are given in milli volts and the current as microamperes as input. The developed software would find : a) Corrosion currents by anodic and cathodic Tafel line extrapolations, b) corrosion rates expressed as mpy, c) Cathodic and Anodic Tafel Slopes, d) Corrosion currents by Stern - Geary method, e) Corrosion currents by Barnatt's method, f) Corrosion currents by Oldham and Mansfeld's method. Details of the Corrocal and its applications to various systems are presented.
