The carbamate turns out to be a good inhibitor of the corrosion of brass (80/20 and 59/41) in 0.5 N sodium chloride, 1.0 n sodium hydroxide and buffer solutions (NaOH and citric acid, pH 4.4‐6.0). The inhibiting effect depends on inhibitor concentration, so that in some cases corrosion may even be stimulated. The inhibitor effect is attributed to the formation of insoluble complexes with the two alloy components.
