Abstract The corrosion process of different Cu-Sn bronzes in NaCl and Na₂SO₄ solutions were examined by electrochemical analysis technologies, including open circuit potential(OCP), polarization curves (Tafel curves), electrochemical impedance spectroscopy(EIS), etc. The microstructure were observed by a digital microscope for evaluating the preferential corroded phase (α phase or δ phase). Electrochemical experimental results revealed that the corrosion resistance of the bronze with high Sn content was superior to the bronze with low Sn content. Through microstructural observations, it was found that the corrosion pits on the α phase were significantly more than that on the δ phase, indicating that the α phase was the preferential corroded phase. This study provides the basic data for the ancient bronze wares protection.
