| 摘 要： | 研究了表面涂覆ＣｅＯ２对Ｆｅ－２３Ｃｒ－５Ａｌ合金９００℃和１０００℃下形成的Ａｌ２Ｏ３膜生长应力的影响。涂覆ＣｅＯ２增大了合金的氧化速率，促进了Ａｌ２Ｏ３膜的起皱同时也增大了Ａｌ２Ｏ３膜的生长应力。涂覆ＣｅＯ２表面形成的起皱的Ａｌ２Ｏ３膜在冷却过程中剥落量较少；而在真空保温过程中应力不容易释放。认为表面涂覆ＣｅＯ２对Ｆｅ－２３Ｃｒ－５Ａｌ的抗氧化并不能起到改善作用。

| Abstract: | The influence of superficially applied CeQ on the growth stresses in A1203 scales forned on Fe- 23Cr-5A1-0.2113 alloy at 900°C and 1000°C has been investigated by using a modified deflection technique. CeQ coating increased the mass gain of the alloy, pmted the convolution of A1203 scale, and increased the graYth oxide stresses. The creep of the alloy has a less effect on the relaxation of the growth stress in the convoluted scale than on that in the plane scale. Although less spallation of the convoluted scale during cooling, CeQ coating had no clear beneficial effect on the oxidation resistance of Fe-23Cr-5A1 alloy. |
