为了研究高温暴露过程中砷杂质在金属/氧化物界面上的偏聚,系统研究了不同Ce含量的含砷钢的等温氧化行为。结果表明,含砷钢在950-1150 ℃范围内的氧化增重随Ce含量从0增加到0.035wt.%而整体降低。在1100和1150摄氏度下,对于0.027和0.035重量%,Ce.此外,Ce的添加可以防止晶界氧化,这减少或甚至消除了在1000和1050 ℃下沿着晶界的可见氧化物颗粒的形成。在1050和1100 ℃氧化的情况下,随着Ce含量从0增加到0.027wt.%,氧化皮/金属界面处的砷富集量首先降低然后随着Ce含量从0.027增加到0.035wt.%而略有增加。这种变化归因于氧化皮的分离行为,形成连续的固体Fe 2SiO 4层和添加Ce促进的含砷稀土颗粒。
In order to study the segregation of arsenic impurities at the metal/oxide interface during high temperature exposure, isothermal oxidation behavior of arsenic bearing steels with various Ce content was systematically investigated. The result showed that oxidation mass gain of arsenic bearing steel in the temperature range of 950-1150 degrees C was decreased as a whole with increasing Ce content from 0 to 0.035 wt.%. At 1100 and 1150 degrees C, the best results are obtained for 0.027 and 0.035 wt.% Ce. Moreover, Ce addition could prevent grain boundaries oxidation, which reduced or even eliminated the formation of visible oxide particles along grain boundaries at 1000 and 1050 degrees C. In case of oxidation at 1050 and 1100 degrees C, the arsenic enrichment amount at the scale/metal interface was firstly decreased with increasing Ce content from 0 to 0.027 wt.% and then slightly increased as Ce content increased from 0.027 to 0.035 wt.%. This variation was attributed to the separation behavior of oxide scale, the formation of a continuous solid Fe2SiO4 layer and the arsenious rare earth particles promoted by Ce addition.
