Unusual surfaces with structural gradients: Investigation of potential gradients on bipolar electrodes during bipolar anodization of aluminum

The electrical potential gradients on aluminum bipolar electrodes (BPEs) subjected to bipolar anodization in an alternating current (AC) electric field were investigated by performing scanning electron microscopy, dyeing the anodized specimens, and measuring the resistance in the alumina films after...
