中文摘要:
      目的 在碳钢表面制备阳极氧化膜,探讨阳极氧化膜的成分组成。方法 采用恒电流阳极氧化法在含0.1 mol/dm3 NH4F 和0.5 mol/dm3 H2O 的乙二醇电解液中,于45#钢表面制备阳极氧化膜。通过SEM、EDS、XPS、Raman、IR、动电位极化测试等技术手段表征所制备的阳极氧化膜。结果 所获阳极氧化膜外观为黄色。电流密度为1 A/dm2 时,氧化膜局部区域出现彩虹色;电流密度为1.5 A/dm2 时,氧化膜颜色较均匀。随着氧化时间的增加,氧化膜颜色变深。阳极氧化膜表面具有特征图案。EDS 分析发现,阳极氧化膜中存在Fe、O、C。XPS 分析进一步表明,阳极氧化膜中还含有F 元素。Fe 2p XPS谱的各项数据均与α-Fe2O3 的较为吻合。拉曼分析表明,电流密度为1.5 A/dm2 的阳极氧化膜的拉曼光谱的峰的数量多于电流密度为1 A/dm2 的。所有氧化膜的拉曼光谱均在1400 cm-1 附近有峰出现,此峰对应于α-Fe2O3。700 cm-1 处的峰对应于FeOOH。红外光谱分析表明,所有阳极氧化膜的红外光谱波形一致,在700~400 cm-1 之间出现振动,540、514、482 cm-1 附近的吸收峰归属于Fe2O3 的振动带,604、672 cm-1 的吸收峰归属于FeOOH。极化测试表明,经阳极氧化处理后,自腐蚀电位上升,自腐蚀电流密度降低。结论 碳钢能够在乙二醇体系电解液中生成黄色阳极氧化膜。电流密度和氧化时间对膜的颜色有影响。膜表面具有特征图案。阳极氧化膜主要含Fe、O、F 等元素。Fe 元素以Fe(Ⅲ)的化学态形式存在于阳极氧化膜中。阳极氧化膜中氧化物主要为α-Fe2O3,FeOOH 也存在其中。阳极氧化处理后的试样的耐蚀性较处理前有所提升。
英文摘要:
      The work aims to prepare an anodic oxide film on the surface of carbon steel and investigate the composition of the anodic oxide film. Anodic oxide film was prepared on the surface of 45# steel in ethylene glycol electrolyte containing 0.1 mol/dm3 of NH4F and 0.5 mol/dm3 of H2O by using constant current andizing technology. Technical means of SEM, EDS, XPS, Raman, IR and potentiodynamic polarization test were adopted to characterize the prepared anodic oxide film. The obtained anodic oxide film was yellow in appearance. When steel was anodized at a current density of 1 A/dm2, local area of the oxide film turned rainbow. However, when the steel was anodized at a current density of 1.5 A/dm2, the color of the aoxide film was uniform. The color of the oxide film got darker as oxidation time increased. The surface of the anodic oxide film showed a characteristic pattern. The EDS analysis indicated that the anodic oxide film contained Fe, O and C. XPS analysis further revealed that the anodic oxide film contained fluorine (F element) as well. Fe 2p XPS spectrum of the film was consistent with that of α-Fe2O3. Raman analysis indicated that, Raman spectra of anodic oxide film prepared at current density of 1.5 A/dm2 contained more peaks than that of anodic oxide film prepared at current density of 1 A/dm2. All Raman spectra had showed peak near 1400 cm-1 corresponding to α-Fe2O3. The peak located at 700 cm-1 corresponded to FeOOH. Infrared spectroscopic analysis indicated that, all anodic oxide films had similar IR spectra, which showed vibration at a range from 700 to 400 cm-1. Absorption peaks near 540 cm-1, 514 cm-1 and 482 cm-1 belonged to vibrational band of Fe2O3. Absorption peaks at 604 cm-1 and 672 cm-1 belonged to FeOOH. Polarization test indicated that self-corrosion potential increased and self-corrosion current density decreased after anodizing. Carbon steel can form yellow anodic oxide film in ethylene glycol electrolyte. The current density and anodization time have effects on the color. The surface of the film shows a characteristic pattern. The anodic oxide film mainly contains Fe, O, F, etc. In the anodic oxide film, the Fe element exists in the form of chemical state of Fe (Ⅲ). Oxides in the anodic oxide film are mainly α-Fe2O3 and FeOOH. The corrosion resistance of sample is improved by anodizing.
