    Abstract: Alternative inhibitors that offer an improvement over tolyltriazole in inhibiting yellow metal corrosion. The dithiocarbamate compounds and their salts were compared to that of tolyltriazole under identical conditions. These comparative tests were conducted in common corrosion testing systems, using both electrochemical corrosion cells and pilot cooling rigs, using various water conditions. The test methods included electrochemical studies such as linear polarization resistance, open circuit potential versus time, Tafel and cyclic polarization.
