摘要：

A F82Hmod. martensitic steel has been tested in lead-bismuth under a gas atmosphere with a H-2/H2O equilibrium of 0.3 to examine the influence of temperature on the oxidation/corrosion process. The temperature range studied was 535-550 degreesC, temperatures just below the temperature transformation of magnetite into wustite. The durations of the tests were 500 and 1000 h and the oxygen concentration in lead-bismuth was between 3 x 10(-7) and 4 x 10(-7) wt%. The results point out the existence of a threshold temperature, around 550 degreesC, above which corrosion occurs and the formation of a protective oxide layer is not possible. Two approaches have been considered to explain this behaviour: (a) a kinetic mechanism more than thermodynamic considerations as the driving force of the oxidation/corrosion in lead-bismuth under low oxygen potential, (b) the possible transformation of magnetite into wustite.
