摘要

The current study investigated the short-term oxidation behaviour of a Si-containing spring steel 60Si2MnA in dry air and wet air (containing 24.8%H2O) at 800 - 1200 degrees C. It was found that within the furnace temperature range of 800 - 1100 degrees C, the oxide scale amount generated in dry air within 20 min at a given temperature was drastically less than that formed in wet air, but within the range of 1140 - 1200 degrees C, the scale amounts formed in the two atmospheres were nearly identical, increasing rapidly with temperature. Significantly different scale structures developed in the two atmospheres within 800 - 1140 degrees C, but the scale structures developed in the two atmospheres at 1170 - 1200 degrees C were similar. A more complex scale structure was observed in the specimen oxidized at a furnace temperature of 1140 degrees C in dry air. The mechanisms responsible for the oxidation behaviour and scale structures developed were discussed.
