The generation of active disinfectants by electrochemical processes (ECA)gains market share due to the lack of need for transportation and storage of dangerous goods as well as the ease of operation. Usually the process involves the use of specific electrodes for electrolysis of water to produce active chlorine species sometimes supported by addition of chlorides to the process water. Thus the influence on the corrosion behavior can vary widely.The work comprises investigation of the passive and repassivation behavior of stainless steels typical for the beverage industry in contact with industrially available disinfectant fluids. Measurements were conducted in electrochemical cells according to ASTM G 150 and with artificial crevices. Results from exposure experiments are shown as well. Specimens made from new sheets as well as from sheets exposed to laboratory cleaning cycles with the disinfectant fluids were investigated. Additionally welded specimens were evaluated to reflect the representative behavior of real installations. The combination of the influence of oxidant and chloride concentration were examined in detail.
