Examination of yellow sand influence on leaching ions from an aluminum alloy and carbon steel by using an artificial corrosion exposure chamber

Abstract

In order to examine the yellow sand influence on leaching ions from a carbon steel plate and an aluminum alloy plate, the behavior of various ion components was examined by using an artificial corrosion exposure chamber under three conditions: (1) pure rain + gas, (2) pure rain + gas + aerosol, and (3) artificial acid rain + gas + aerosol.
It was found that only the leaching of Mg ion from a aluminum alloy plate under conditions (1) and (2) showed an accelerating tend by the yellow sand atomizing. Conversely, however, leaching of all other ions from both boards under all conditions was inhibited by the yellow sand atomizing.
