Abstract
Current fluctuations during general corrosion of stainless steel in su lfuric acid (H2SO4) were studied experimentally and analyzed using a s imple electrochemical model. Stochastic behavior of the metal-electrol yte interface in the model was based upon the assumption that elementa ry fluctuation sources were related to fluxes of electrons that pass f rom a metal to electron-acceptor ions in solution. The number of succe ssful electron transfers obeyed a Gaussian distribution, from which th e corrosion current density (i(corr)) and transfer coefficients could be determined.
