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。
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 Al2O3, Fe2O3, Fe3O4 and FeO. These phases distribute unevenly. The protective Al2O3 film firstly forms and preserves the coatings from further oxidation.
