Abstract

The influence of vacuum annealing treatments on the oxidation rate of Co-10 w/o Cr has been studied at 900°C and 1100°C in 100 Torr oxygen. The oxidation rate posttreatment has been found to decrease markedly with the length of the vacuum annealing period. At 900°C this effect is maintained for all periods of reoxidation studied but at 1100°C the effect of vacuum annealing disappears after a period of slow reoxidation. It is assumed that the decrease of the oxidation rate is due to an increase in the amount of CoCr2O4 in the inner layer.
