摘要
利用高温氧化处理Fe-24Cr-4Al合金表面,制备了Fe-24Cr-4Al合金表面氧化膜。并采用X射线衍射仪、光学金相显微镜、扫描电镜及能谱检测等多种组织与形貌表征手段,对Fe24Cr-4Al合金表面氧化层进行了显微组织的表征以及显微硬度的测定。结果表明:Fe-24Cr4Al合金最佳氧化温度为1250℃,此温度下可得到平整性和致密度较好的氧化膜,且氧化膜具有较高的硬度。
The surface oxide film of Fe-24Cr-4Al alloy was prepared by high temperature oxidation treatment.By means of X-ray diffraction,optical metallographic microscope,scanning electron microscope and energy spectrum analysis,the microstructure and hardness of the oxide layer on the surface of Fe-24Cr-4Al alloy were characterized.The results show that the optimal oxidation temperature of Fe-24Cr-4Al alloy is 1250℃.At this temperature,a smooth and dense oxide film can be obtained,and the film has a high hardness.
