Effects of size and position of an unconnected aluminum electrode on bipolar anodization in an AC electric field

Abstract The effects of the size and position of an aluminum bipolar electrode (BPE) on the uniformity of formation of anodic porous alumina in an alternating current electric field were investigated. Anodized specimens were dyed, and the resistance was measured after the specimens were anodized aga...
