Resumo: | Abstract DBS corrosion resistance effect on MS immersed in a 0.25 mol/L H2SO4 solution has been evaluated at room temperature, WL method, from which CR and IE(%) were obtained. The corrosion IE% increased with higher inhibitor concentrations. The CR decreased with higher DBS concentrations, since it blocked the MS active site, forming a protective film on its surface, which was confirmed by electrochemical studies and surface analysis techniques, such as FTIR and SEM. EDAX was used to analyze the elements present on the MS surface, after its immersion in 0.25 mol/L H2SO4, without and with DBD. The MS surface smoothness and roughness (polished and corroded) and the inhibitor have been evaluated by SEM and AFM. |
