Abstract：Although dewing is well recognized to play an impor tant role in the atmospheric corrosion of metals, direct observation of dewing p rocess has not been reported. In order to demonstrate the phenomenon in laborato ry, a simple experimental arrangement was set up. Since dewing is a result of mo isture condensation when metal surface is chilled down below the dew-point tempe rature of the air, a semiconductor cooling unit was adopted to cool the plate sp ecimen. Thus dewing process could be observed under metalloscope, and photograph s of the dew droplets could be taken when necessary. Initially minute droplets appeared upon cool surface. Then adjoining drops merged into a larger one and so drops grew gradually. Finally a thin water film covered entirely the specimen s urface. In this way various influencing factors could be examined with ease. Wh en the specimen surface was covered with dust, dewing took place surrounding the dust with priority. On the salt contaminated surface dewing was much easier. Th ese illustrated unambiguously the enhanced effect of dust and salt contaminated on atmospheric corrosion.
