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 …

Pitting Corrosion Of Ni_Based Alloy In Thiosulfate_Ion Containing Chloride Solutions, Yungfa Lee, Tingyu Wang, Wenta Tsai
Journal of Electrochemistry
The effect of thiosulfate ion on the pitting corrosion behavior of Ni_Based Alloy 690 in chloride solution was investigated.In plain sodium thiosulfate solution,Alloy 690 was immune to pitting corrosion. However, the addition of low concentration of sodium thiosulfate can enhance the initiation of pitting corrosion of Alloy 690. Nevertheless, inhibition of pitting corrosion was observed at high concentration of addition.
