报告题目: Overview on Corrosion in supercritical fluids

Abstract: After a short presentation of the CEA Corrosion department, an overview on the corrosion behaviour of metallic metals and alloys under pressure and temperature conditions appropriate for supercritical fluids will be presented. Steels, including stainless steels, and nickel base alloys are the main alloys investigated in supercritical environments. In supercritical water (SCW), the review highlights how SCW density changes the corrosion mechanisms. In other supercritical fluids like supercritical CO2, authors observed that no corrosion occurs in pure SCF but the water content is a key parameter. Temperature, water and pollutants are the major factors leading to increase uniform or localized corrosion rates.
