摘　　要：利用静态增重法研究了310S奥氏体不锈钢丝在700、800、900、1000℃下的氧化特性,采用扫描电镜、能谱分析和X射线衍射仪对该材料表面的高温氧化膜形貌及物相进行了分析。结果表明：310S奥氏体不锈钢丝在1000℃下抗氧化,且氧化动力学曲线遵循抛物线规律;氧化膜主要由铁的氧化物（Fe2O3、Fe3O4）、铬的氧化物（Cr2O3）和具有尖晶石结构的Ni Cr2O4、Fe Cr2O4组成。The oxidation characteristics of 310S austenitic stainless steel wire at 700 ℃, 800 ℃, 900 ℃ and 1000 ℃were studied by TGA method. The morphology and phase composition on surface of the material were analyzed by SEM,EDS and XRD. The results show that 310S austenitic stainless steel wire exhibits oxidation resistance at 1000 ℃ and theoxidation kinetic curves follows parabola rule; the oxide scale mainly consists of iron oxides （Fe203, Fe304）, chromium oxides（Cr203） and NiCr204 and FeCr204 with spinel structure.
