Resumen
In this study, an electrochemical syringe droplet cell was developed and used to evaluate the pitting corrosion resistance of Type 304 stainless steel. The cell was also adapted to perform measurements in deaerated environment, by means of continuous N2 injection. The results obtained with the syringe cells, in both conditions (aerated and deaerated), were reproducible and free of crevice corrosion because the cell configuration does not allow obtaining this condition. The proposed cell demonstrates coherency with data acquired using conventional cell arrangements, being a potential alternative to study pitting corrosion of passive metals.
