A Study Of The Corrosion On Bronze, Hongfan Zhu, Hao Zhou
Journal of Electrochemistry
The bronze is the treasure in chinese metallic antique, which was typified by product in Shang_Zhou period (three thousands years ago). Because of corrosion, archaeological messages,such as inscription and pattern on the surface of bronze, would be damaged then the value of bronze antique decreased. The bronze disease is a common disease which forms powdery rust on the surface of bronze in atmospheric environment, the powdery rust emerge from under incrusted rust, then spreads, and eventually leads to bronze damaged. This paper investigates the bronze disease. According to the chemical and electrochemical tests in simulated occluded cell, the variation in …

A Study On The Cathode Protection Potential Against Pitting Corrosion, Chunchun Xu, Youping Liu, Xiaobo Zhang, Xuhui Zhao
Journal of Electrochemistry
The methods have been developed to determine the protection potential against pitting corrosion. They are based on the theory that the pitting protection potential(Ep) is actually the transition potential of the direction of current between the occluded cell and the external surface (ET).ET lasts from -220 mV to -440 mV(SCE), the lowest of which can be considered as cathode protection potential. The Ep values determined with cyclic potentiodynamic polarization method is included in the ET with above methods.
