The Electrochemical Behaviors of HSn70-1A Brass in Polluted Freshwater

Abstract:

The corrosion behaviors of HSn70-1A brass in polluted freshwater were investigated by electrochemical measurements. Results of immersion experiments in eutrophic freshwater and pollution-free water showed that the dissolved oxygen content in the water was a key factor in determining the corrosion rate of HSn70-1A brass. Because the dissolved oxygen content in the polluted freshwater was lower than that in pollution-free freshwater, the corrosion rate of HSn70-1A brass in polluted freshwater was also lower than that in the pollution-free water. Moreover, electrochemical measurements in simulated freshwater showed that phosphoric compounds had an inhibiting influence on the corrosion of HSn70-1A brass while the nitric compounds had little this inhibiting effect.
