摘要：

A model ferritic Fe-25wt% Cr alloy exposed to an Ar-60CO2-20H2O gas mixture at 650 degrees C experienced rapid oxide scale growth and simultaneous internal carburization. When a deposit of NaCl-KCl was present on the alloy surface, it developed a more porous oxide scale and more extensive carburization. In the absence of salt, alloy additions of Si+Mn led to improved protection: slow oxide scaling and no carburization. In the presence of salt, this protection was much reduced. These effects are discussed in terms of oxide volatilisation and ferrite chromium concentration depletion by carburization.
