Role of ozone and UV light in atmospheric corrosion of Ag

摘要

The effects of ozone, UV, and humidity on the atmospheric corrosion of Ag were studiedrnusing coulometric galvanostatic reduction as well as microscopy. A variety of environmentsrncontaining different levels of the variables was examined. Ozone and UV were found torngreatly accelerate the corrosion rate of Ag; the presence of both was required for fastrncorrosion to occur.
