dc.description.abstract Electrochemical cells commonly employ liquid electrolytes. These cells can present limitations, like studying irregular surfaces or the generation of crevices as a result of delimiting the surface of the working electrode. The current study has developed a gel electrolyte based on agar-glycerol as an alternative to the saline aqueous solutions often used in anodic polarization tests of stainless steels. Texture analysis and rheological tests were performed to characterize the gel electrolytes and determine the best composition in function of their characteristics of adaptability to provide a suitable contact to complex surfaces. Comparisons between typical aqueous and gel electrolytes in ionic conductivity and electrochemical measurements (anodic polarization curves) were carried out to validate the gel electrolytes for the evaluation of pitting corrosion behavior of metals.
