摘　　要：以H2SO4为电解液对高纯铝箔进行阳极氧化,用涡流测厚仪分析制备工艺参数对多孔氧化铝膜厚度的影响。结果表明,在一定电解液浓度及电解电压下,氧化铝膜厚度随电解液浓度及电解电压的增加而增大,但过高的电解液浓度及电解电压均会造成氧化铝膜的快速击穿。氧化铝膜厚度随电解时间的增加而增大,但初期的增长速度较快,后期随电解时间的增加变化缓慢。在一定温度范围内氧化铝膜的厚度随温度的升高而增加。High-pure aluminum foil is oxidized in anodic with H2SO4 as electrolyte.The effect of the technological parameters on thickness of oxide aluminum membrane is investigated by using eddy current sensor thickness.The results show that the thickness of oxide aluminum membrane is increased with the increase of electrolyte concentration and voltage,but the exorbitant electrolyte concentration and electrolysis voltage are prone to rapid breakdown of aluminum foil.The thickness of oxide aluminum membrane is increased with the increase of the electrolysis time,however the growth speed of oxide aluminum membrane thickness is firstly fast and then becomes slow.Within a certain range of temperature,the thickness of oxide aluminum membrane is increased with the increase of the electrolysis temperature.
