摘要
采用自制脉冲恒流电源,对硬质铝合金2A12在高、低硫酸浓度下的阳极氧化工艺进行研究。结果表明:2A12合金在低硫酸浓度中进行硬质阳极氧化,氧化膜的硬度和膜层厚度较在高浓度硫酸溶液中的高;无论是硫酸溶液浓度高低,硫酸溶液浓度、槽液温度、氧化电流密度等均影响2A12铝合金硬质阳极氧化膜的硬度和膜层厚度。
The anodizing technology of aluminum alloy 2A12 was studied in sulfuric acid with different concentration by self-made pulsed constant current apparatus. The results shows that the microhardness and film thickness of aluminum alloy 2A12 in low sulfuric acid solution are larger than these in high sulfuric acid solution. Whether or not sulfuric acid concentration is high or low, sulfuric acid solution, bath temperature and current density affect the micro-hardness and film thickness of aluminum alloy 2A12.
