Abstract
Abstract Severe corrosion damage occurs in high subcritical and supercritical aqueous systems (SCAS), and few materials can withstand those harsh working conditions. In this study, two corrosion mechanisms, “chemical oxidation” (CO) and “electrochemical oxidation” (EO), have been postulated to describe the corrosion processes in SCAS, depending upon the density and dielectric constant of the systems. Electrochemical emission spectroscopy (EES) is used to differentiate between the two corrosion mechanisms, by postulating that only the electrochemical mechanism gives rise to spontaneous fluctuations in current and potential. EES is used to measure the instantaneous electrochemical corrosion activity in SCAS based on the assumption that a proportional relationship exists between the electrochemical current noise and the corrosion current. Experiments on Type 304 (UNS S30400) stainless steel (SS) and titanium in water, 0.01 m hydrochloric acid (HCl), 0.01 m sulfuric acid (H2SO4), and in 0.01 m sodium hydroxid...
