| 中文摘要: |
| 温度对铝合金硬质阳极氧化膜的质量有显著影响,低温条件下制备的氧化膜质量远优于常温氧化膜。研究了低温(- 6～ - 9℃)条件下LY12铝合金硬质阳极氧化工艺,分析了氧化温度、时间、电流密度对氧化膜颜色、厚度、显微硬度的影响,探讨了氧化电流密度与氧化电压的关系。结果表明,在氧化温度- 6～ - 9℃、电流密度1.6～ 1.8 A/dm2、氧化时间60 min的条件下对LY12铝合金进行硬质阳极氧化,可以达到工件硬质阳极氧化膜厚35～ 45μm,硬度380～ 450HV的要求,且氧化膜颜色深而均匀,主要含C,O,Al,P,S元素。 |

| The temperature had a remarkable influence on the quality of hard anodic oxidation films on aluminum alloys, and particularly, the quality of anodic oxidation films prepared at low temperature was far better than that prepared at room temperature. The preparation technology of hard anodic oxidation on LY12 aluminum alloy at low temperature was studied. The effects of oxidation temperature, oxidation time, and current density on the color, film thickness, and micro-hardness of oxidation films were investigated respectively, and the relation between oxidation current density and oxidation voltage was discussed as well. Results show that the hard anodic oxidation film has an uniform and dark surface with a thickness of 35～ 45μm and a hardness of 380～ 450 HV, when the anodic oxidation film is obtained at temperature of- 6～ - 9℃ , current density of 1.6～ 1.8 A/dm2 and oxidation time of 60 min. The surface compositional analysis reveals that the anodic oxidation film consists of C,O,Al,P,and S,whereas no copper elementis detected. |
