Simulating steam oxidation of high temperature plant under laboratory conditions: practice and interpretation of data

Abstract

Specimens of ferritic and martensitic steels have been exposed to steam atmospheres at 550 °C using three different experimental procedures. Slight differences in scale growth kinetics were observed but the major differences were in the morphology of the oxide scales that were formed. The microstructures of the scales have been compared with those formed on similar materials during service

Effect of Total Pressure and Furnace Tube Material on the Oxidation of T22 in Humidified Air

“…Studies at elevated pressure showed changes in the high temperature corrosion behavior, as reported e.g., for dry air [16], supercritical CO 2 [17][18][19][20][21] or carburizing atmospheres [14,22]. Corrosion issues in steam turbines have initiated research on water vapor-induced oxidation at elevated pressure in static or flowing pure steam [17,[23][24][25][26][27][28]. In these studies, Fe-and Ni-base alloys were tested.…”

Acoustic emission analysis on tensile failure of steam-side oxide scales formed on T22 alloy superheater tubes

“…10 Lots of research efforts have, thus, been performed on steam-side oxide scales. However, the fact is that, although the high temperature steam oxidation mechanism has been extensively investigated in the past years, [11][12][13][14][15] there are still lots of issues associated with the mechanical integrity of the steam-side oxide scales that need more research attention. Among these issues, of special interest are the critical failure resistance and the damage mechanism of the oxide scales.…”

Modeling gas turbine materials’ hot corrosion degradation in combustion environments from H2‐rich syngas

“…The application of these statistics to hot corrosion metal losses are also illustrated in ISO standards . More recently, this statistical approach to corrosion degradation has been used in a range of environments, for example, .…”

“…The application of these statistics to hot corrosion metal losses are also illustrated in ISO standards [22,26,27]. More recently, this statistical approach to corrosion degradation has been used in a range of environments, for example, [28,29]. Post-exposure, samples were imaged by a scanning electron microscope (SEM) equipped with energy dispersive X-ray spectroscopy (EDX) to study the microstructural evolution.…”
