| 摘要: |
| 研究了304不锈钢在800℃下空气中分别氧化0.5，2，10，25，100和200 h后，其氧化增重、表面形貌和元素组成的变化以及高温氧化对其红外发射率的影响。研究结果表明，氧化初期氧化增重迅速，随着氧化时间增加，合金增重速率逐步降低。合金表面氧化初期以形成Fe氧化物为主，氧化时间增加，表面组成由Fe氧化物转变为大的片状Cr、Mn氧化物。抛光后未经氧化的304不锈钢的红外发射率极低，随着氧化时间的延长红外发射率迅速增大。 |

| Abstract: |
| The effect of 304 stainless steel oxidation at 800℃ for 0.5, 2, 10, 25, 100 and 200 h, respectively, on its weight gain, surface microphotograph, composition, and infrared emissivity were investigated in the paper. The results show that, with increasing the oxidation time, the weight gain rate decreased gradually. At the initial stage of surface oxidation, Fe oxide was mainly formed. The surface composition changed from Fe oxide to large flake Cr Mn oxide with the increasing of oxidation time. Polished and unoxidized stainless steel 304 showed low infrared emissivity, the infrared emissivity increased rapidly with the extension of oxidation time. |
