Název v původním jazyce

In-situ electrochemical impedance and noise measurements of corroding stainless steel in high-temperature water

Popis výsledku v původním jazyce

An in-situ corrosion study of austenitic stainless steel 08CH18N10T in high temperature water was performed. The material under study is used in the construction of steam generator of PWR (Pressurized Water Reactor) nuclear power stations and is similarto AISI 321 stainless steel. A detailed analysis of the impedance data is presented identifying in the impedance spectra contributions of oxide, corrosion reaction, double layer and diffusion process. A good agreement was found between corrosion data from electrochemical impedance spectroscopy (EIS) and that from electrochemical noise (EN) measurements. It was confirmed that the oxide response cannot be attributed to the overall oxide layer but only to the part corresponding to the space charge layer, thus indicating the semi-conductive character of the oxide.
