【Abstract】 The high temperature corrosion behavior of T91samples with three kinds of surface condition at 650 ℃ in gas mixture of SO2 were studied, namely the original surface of T91, the T91surface treated by shot blasting and the T91 surface with the CeO2 film deposited after shot blasting treatment. The curve of corrosion rate and time was given and the corrosion mechanism was discussed. The effect of the two kinds of surface treatment techniques on the high temperature corrosion resistant performance of the T91 in SO2 gas mixture was analyzed.更多还原
