| 摘 要： | 利用离心自蔓延高温合成技术，在普通碳素钢管的内壁涂敷一层厚度均匀的Ａｌ２Ｏ３ 陶瓷层．研究表明，在Ａｌ＋ Ｆｅ２Ｏ３ 反应体系中，适当增加配方中Ａｌ或ＳｉＯ２ 的加入量，化学反应趋向于完全，而增加ＣｒＯ３ 的加入量却得到相反的结果；在Ａｌ＋Ｆｅ２Ｏ３ 体系中同时加入ＳｉＯ２ 和ＣｒＯ３，显著降低了陶瓷层的孔隙度

| Abstract: | A uniform ceramic layer can be formed onto the inner wall surface of a plain carbon steel pipe by centrifugal SHS technique. It is proved that reaction of Al+Fe 2O 3 occurs more completely by increasing both Al and SiO 2 additives. However, an adverse result is gained by increasing CrO 3 additive. By adding SiO 2+CrO 3 additive in the Al+Fe 2O 3 system, the porosity in ceramic layer is markedly reduced. |
