Název v původním jazyce

Corrosion behaviour of welded HR3C steel under supercritical water conditions

Popis výsledku v původním jazyce

Supercritical water (SCW) is a promising medium with a broad spectrum of potential applications in the industry. However, the absence of appropriate structural material able to withstand the severe corrosive conditions of SCW still limits its utilization. Therefore, this work is focused on broadening of data related to corrosion behaviour of HR3C steel under supercritical water conditions. The HR3C is austenitic steel with a good high temperature corrosion resistance and creep strength in flue gas environment. The studied samples of HR3C with weld joint were exposed under conditions of SCW (600 °C and 25 MPa) up to 1000 h. Subsequently, the corrosion rate was evaluated on the basis of measured weight changes of the samples. The effect of SCW on the microstructure stability was verified via light, electron microscopy and measurement of microhardness. The oxide layers formed during the expositions were further analyzed by measurements of electrochemical impedance spectroscopy as well as
