T1 - Susceptibility of 304 stainless steel to crevice corrosion in electrochemically active fluids T2 - Proceedings NACE International Corrosion Conference 2019 N2 - The susceptibility of AISI 304 stainless steel to crevice corrosion on the effect of contact with electrochemically active fluids was investigated using exposure and stepwise potentiostatic polarisation. Crevice materials made up of 304 SS and Polyether ether ketone (PEEK) forming two kinds of crevices including 304 SS-to-PEEK and 304 SS-to-304 SS were tested.

Savjetovanje o zaštiti materijala i industrijskom finišu Kormat 2016 N2 - The generation of active disinfectants by electrochemical processes 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. The resulting ECA (ElectroChemically Activated) solutions can cause corrosion due to the content of free active chlorine (FAC) or due to the chloride content of the process solution. These fluids are widely used because they show a good chemical and microbiological stability, are well suited for the standard cleaning procedures and allow reducing germ concentrations to meet hygienic standards. The influence of the respective agents to alloy 1.4301 is investigated by storage experiments and by electrochemical investigations. The results show, that the influence of chlorides is higher for short-term experiments. ECA-Fluids with low chloride concentrations are preferable. The goal of the investigations is to creat evaluation guidelines for the application parameters to provide a sufficient cleansing effect without causing corrosion of the surfaces. T2 - 22.
