  • Abstract
    Experiments were conducted to show the effects of gas flow velocity in the test chamber, the kinds of corrosive gases, and their concentration on the tarnish kinetics of copper and silver. The gas flow velocity was varied from 0.4 cm/s to 42 cm/s. H2S was selected as the corrosive gas in the single gas test condition, and H2S, NO2, and SO2were selected as the corrosive gases in complex conditions, at room temperature and a relative humidity of 70 percent.
