Abstract The oxidation behavior of a ferritic stainless steel alloyed with elements, W and Ce, was studied at 950―1100 °C for up to 100 h. The oxide film was compact and uniform on the addition of Ce, and the number of defects at the oxide/metal interface was significantly decreased such that it exhibited good adhesion. The addition of Ce or combination of Ce and W reduced the number of dissolved Laves phase (Fe,Cr,Si) 2 (Nb,Mo) at 1000―1050 °C, which precipitated within the grains or at the grain boundaries. The inward growth of oxide film was effectively hindered by Laves phase.

含W和Ce铁素体不锈钢的高温氧化行为

摘要 研究了含有 W 和 Ce 元素的铁素体不锈钢在 950-1100 °C 下长达 100 小时的氧化行为。添加Ce后氧化膜致密均匀，氧化物/金属界面缺陷明显减少，具有良好的附着力。Ce的添加或Ce和W的组合减少了在1000-1050°C时溶解的Laves相(Fe,Cr,Si) 2 (Nb,Mo)的数量，这些相在晶粒内或晶界处析出。Laves相有效地阻碍了氧化膜的向内生长。
