摘要：
The oxidation of an oxide-dispersed Cr-rich alloy has been investigated in air up to 1300 degrees C. The deduced parabolic rate constant, k(p), agrees with literature values for pure Cr and Cr-Fe alloys without yttria addition. The electrical resistance, which is dominated by the oxide scale, is estimated as a function of operation temperature, for an operation time of 10000 h. At 850 and 1000 degrees C the area-specific resistance due to the Cr2O3 scale, assuming a perfect contact to the metal, is estimated to be approximate to 100 m Omega cm(2).
