Determination of the limiting current density through potential step measurementsFuchs-Godec, Regina ; Petek, Aljana ; Doleček, ValterProcesses such as anodic dissolution, prepassive film formation (salt and/or oxide, hydroxide film), and passive film formation are in the initial stage controlled by diffusion. Information about the ... value of the limiting current density is needed for understandihg the kinnetics of passive film formation. In this study an alternative method, suitable for the determination of the id through potential step measurements, is proposed. The method is based on the assumption that the reaction cannot proceed faster than that allowed by the id. In this case, themaximum reaction rate corresponds to the current density at the inflection point of the i-t curve, and this current density is identified as the limiting current density. This method was used to determine the id values of some Cr-13 % stainless steels at five passive potentials in mixtures of 0.1 M H2SO4 + 0.1M Na2S04 with different pH values. The results for the limiting current density were compared with the corresponding id values, obtained from the diffusion overvoltage equation. The agreement between the two methods is satisfactory.Source: Indian Journal of Chemical Technology. - ISSN 0971-457X (Vol. 9, Sep. 2002, str. 438-441)Type of material - article, component partPublish date - 2002Language - englishCOBISS.SI-ID - 7411478
