Abstract
The purpose of this study is to clarify corrosion mechanism of a duplex stainless steel (DSS) through dissolution behavior of a ferritic phase and austenitic phase, respectively. A single phase specimen ([α] or [γ] phase specimen) which has chemical composition of each phase of a DSS was prepared by preferential dissolution of the DSS, and dissolution behavior of each phase specimen was investigated. The [α] specimen showed a less-noble corrosion potential compared to the [γ] specimen. The change of the corrosion potential of the DSS was located somewhere between those of each phase specimen. The [α] specimen showed a less-noble active peak compared to the [γ] specimen. The current density value of the DSS was located between the current values of each phase specimen. It was clearly shown that the corrosion mechanism of a DSS could be described through the dissolution behavior of single phases such as α phase and γ phase.
