Abstract

Some studies have been performed on the application of the supercritical fluid environment to the extracting separation, the decomposition of the pollutant and the synthesis of the organic compound. One of the problems to apply the supercritical fluid is the selection of the reliable construction material for this environment. Some examinations have been done regarding to the localized corrosion and the stress corrosion cracking, but the electrochemical behavior of metallic materials has not been studied in this environment.
The results of the electrochemical examination in the carbon dioxide supercritical fluid mixed with nickel-plating solution, which is acidic and containing chloride, are introduced in this paper. The electrochemical characteristics of the materials in this environment become obvious from this study. It is also estimated from this examination that 329J4L stainless steel and C276 alloy can be use for the construction materials in this supercritical fluid environment.
