A corrosion study of SS-304L was carried out exposing the material to LiBr-H2O solution 50% (wt.) at 70{degree sign}C for 20 days, applying the electrochemical noise technique and polarization curves. The aim of this work was to determine the corrosion rate and the type of corrosion of SS-304L. The corrosion evaluation was supported by optical observations of corroded specimens and EDX analysis of corrosion products. The dissolved corrosion products in LiBr solution were also analyzed by the atomic absorption technique. To obtain the corrosion rates, the noise resistance from ENT was calculated, and then the Stern-Geary equation and the Faraday Law were used. In general, the results of corrosion rates showed an oscillatory behavior, obtaining a cumulative mass loss of 6.11 mg/cm2. The electro-chemical signals showed important evidences of localized corrosion, showing significant transients of high magnitude, but also low amplitude and high frequency noise. The pitting indexes mainly lie in the mixed corrosion zone, being in agreement with visual observations of corroded samples. Optical transmittance measurements of corrosive solution with dissolved Fe, Cr, and Ni species are also presented.
