EIS evaluation of steady-state characteristic of 316L stainless steel passive film grown in acidic solution

Résumé

The EIS is a useful tool to characterize corrosion behavior of stainless steel, especially when it comes to the properties of the passive film. A specific electrical equivalent circuit was therefore developed to investigate the diffusion/migration of vacancies occurring within this oxide as described in the point defect model. This circuit was used at 20 degrees C, 60 degrees C and 80 degrees C. The vacancy diffusion coefficient calculated was found to be close to 10(-14) cm(2) s(-1). (C) 2012 Elsevier B.V.
