Effect of the Solution Condensation Process of Acid Salt Tests on Corrosion Behavior

Abstract

Recently, cyclic corrosion test containing acetic acid or nitric acid has been carried out to investigate the corrosion by acid rain and the corrosion behavior of Al alloys. The effects of solution condensation on the corrosion behavior of an Al alloy and a stainless steel in these tests were investigated. The change of pH and ion concentration of Cl^‒, NO₃^‒, CH₃COO^‒ with solution condensation were investigated. The polarization measurements were carried out in condensed solutions and the correspondence between the result of the CCT and that of polarization measurements was analyzed.
