采用正交试验方法 ,结合扫描电镜 (SEM)研究了在硫酸溶液中进行阳极氧化时电压、温度、浓度对氧化铝膜的膜厚、表面孔径和孔排布规律的影响。结果表明 ,影响氧化铝膜的膜厚、表面孔径的主次因素顺序为电压、温度、浓度 ,此外由于电压、温度、浓度三者共同影响着阳极氧化的速率和反应过程的稳定性 ,从而影响最终的多孔膜的有序度 The effects of voltage, temperature and concentration on the film thickness, surface pore size and pore arrangement of alumina film were studied by orthogonal test and scanning electron microscope (SEM). The results show that the order of the primary and secondary factors affecting the film thickness and surface pore size of the aluminum oxide film is voltage, temperature and concentration. In addition, the voltage, the temperature and the concentration all affect the rate of the anodic oxidation and the stability of the reaction process, thereby affecting The degree of order of the final porous membrane
