Anodic polarization curves were measured on stainless steel electrodes in KC1 solution up to 1.0N. The existence of maxima in the potential time curve was verified, and the time for the potential to decay to +0.5 v vs. SCE was measured. This depends on the time at open circuit just before measurement. For less than 3 min, it is a function of this time, for more, there is no effect, at least over one order of magnitude of the applied anodic current density. The data support the view that the effect of Cl− can be due to sorption phenomena, without assuming an oxide film.
