For silver, silver chloride (AgCl) and silver sulfide (AgS) were formed. Although the volcanic activity had greatly subsided, the atmospheric corrosion of copper and silver plates exposed on Miyake Island was mainly affected by volcanic gases, wet–dry cycles in the environment, and sea-salt ...
Atmospheric Corrosion of Copper and Silver 喜欢 0 阅读量: 123 作者: DW Rice 摘要: The corrosion rate of copper in laboratory tests is shown to be a sensitive function of relative humidity, sulfur dioxide, hydrogen sulfide, ozone, hydrogen chloride, and chlorine concentrations. Observed indoor ...
Based on stress corrosion cracking (SCC) studies on brass, and on Ag–Cd alloys (a model alloy used to reproduce the behaviour of brass), it was found that both pure copper and pure silver are susceptible to SCC in 1 M copper(II) nitrate and in 1 M silver nitrate aqueous solutions, ...

Two complementary models to describe the long-term corrosion of silver-copper coins, based on potential rate laws for smooth corrosion and those combined with diffusive law, for gross corrosion, are proposed. Theoretical kinetics can be tested using signatures of copper and silver corrosion products ...

The amounts of metals liberated from silver soldered stainless steel and cobalt-chromium orthodontic wires were measured. Measurements were taken after 3 days and 24 days immersion in 0.9 % sodium chloride solution. High amounts of copper and zinc and some cadmium from the silver solder were ...
