| 摘 要： | 采用高速电弧喷涂技术(HVAS)在20G钢基体上制备了Fe-Al金属间化合物涂层，测试了涂层在800℃下的氧化性能．结果表明，Fe-Al涂层的氧化动力学曲线近似呈现对数规律，其在5h后的氧化增重低于20G钢；涂层的氧化物为Al2O3、Fe2O3、Fe3O4和FeO等，且其分布不均匀；涂层表面优先形成具有保护性的Al2O3膜，阻止了涂层的进一步氧化。

| Abstract: | The Fe-Al intermetallic coatings have been prepared by high velocity arc spraying (HVAS) technology on 20G steel and the oxidation performance of Fe-Al coatings has been studied.The results demonstrate that the kinetics curve of oxidation approximately follows the logarithmic law and oxidation velocity of Fe-Al coatings is less than that of 20G steel after 5 hours.The composition of the oxidized coating is composed of Al 2O 3,Fe 2O 3,Fe 3O 4 and FeO.These phases distribute unevenly.The protective Al 2O 3 film firstly forms and preserves the coatings from further oxidation. |
