ABSTRACT OF THE DISCLOSURE A method is provided herein for the electrochemical corrosion pro- tection of a stainless steel member which is periodically subjected to vary- ing concentrations of a corrosive oxidizing solution of chloride ions, e.g., a partly submersed, rotating, stainless steel drum in a vat containing a cor- rosive, oxidizing, chloride-containing bleach liquor. The method comprises the step of impressing a protection potential to the stainless steel member, e.g., drum at a predetermined voltage in the range of -600 to ?400 ?V Ag/AgCl. This predetermined voltage is sufficiently low to draw the stainless steel into a passive corrosion protection zone. However, that voltage is not suf- ficiently low to draw the stainless steel into a zone of uniform corrosion. Specific means for the placement of the anode in the vat are also provided.
