The corrosion tendency of the SS304 disc samples was also evaluated in the S1, S2 and S3 media individually by electrochemical impedance spectroscopy and Tafel polarization tests conducted at a constant temperature of 37 ⁰C after 14 days of incubation. In the three-electrode electrochemical cell, the SS304 disc samples were connected to the working/working sense lead of the cell cable connected with the Gamry Potentiostat (Interface 1000). In this cell, a Pt wire and Ag/AgCl electrodes were used as auxiliary and reference (0.199 V vs. SHE) electrodes, respectively.
