Název v původním jazyce

Corrosion behaviour of structural steels exposed in supercritical water

Popis výsledku v původním jazyce

Different types of creep-resisting steels were exposed in supercritical water (SCW) experimental loop (580-600°C, 25MPa) for up to 1000 hours under varied conditions (oxygen concentration, pH, subcritical-supercritical transition etc.). Materials under study included highly alloyed austenitic steels and ferritic-martensitic steels having chromium content between 8,5 and 12%. All the materials selected for the tests are designated for the construction either of supercritical boiler pressure parts or of turbine components. Chemical composition, electronic and chemical structure, morphology and thickness of oxide layers formed during interaction with the SCW were ex-situ characterized by the electrochemical methods and by the methods of surface analysis (XPS, Raman spectroscopy). The electrochemical approach included electrochemical impedance spectroscopy (EIS), capacitance vs potential measurements (the Mott-Schottky plots) and double loop electrochemical potentiokinetic reactivation tes
