“…This potential is used to describe the corrosion resistance of metals, particularly in aggressive solutions. The higher the passivation potential, the stronger the corrosion resistance in the corrosion media . However, when the Sn content was increased to 26.8%, the corrosion potential reached its lowest value.…”

“…The higher the passivation potential, the stronger the corrosion resistance in the corrosion media. [13] However, when the Sn content was increased to 26.8%, the corrosion potential reached its lowest value. This was because the content of the Cu-Sn solid solution is the highest at this Sn content.…”

“…There has actually been a significant amount of research on chloride media. [11][12][13][14][15][16] It has been proved that the passive layer on copper consists of copper oxides and/or chlorides. Sometimes complex ions may also be formed, that is, CuCl 2− and CuCl 3− , at different pH values and ion concentrations.…”

The corrosion behavior of synthetic Cu–Sn bronze alloys with six different Sn contents was examined through an electrochemical test and a synthetic test in a simulated corrosive medium. The mechanism of corrosion and the morphology of the corroded surfaces were characterized through field emission scanning electron microscopy equipped with energy‐dispersive spectroscopy. At the corrosion potential, the corrosion behavior appears to be determined by the charge transfer step and the diffusion process. It was found that the bronze‐IV (Cu–26.8Sn) specimen exhibited the best corrosion resistance, as evidenced by a low corrosion current density and a high impedance. This improvement resulted from an increase in the content of the Cu–Sn solid solution in the alloy, which was conducive to forming a relatively more protective passive film on the surface of the bronze alloy. This finding would be valuable in the anticorrosion protection of archeological artefacts after their excavation.
