Anodic oxide films were formed on high purity aluminium (99.996%) in a glycol–borate electrolyte. Following aging of the films under zero field conditions either at room temperature or 60 °C the electrodes were returned to the electrolysis cell where the anodic overpotential was increased rapidly until a predetermined value was reached, then maintained constant. The ensuing current transients were recorded and analyzed. As little film growth occurred during these measurements the conditions correspond closely to constant field strength. For sufficiently low field strengths the observed current decreased monotonically with increasing time. No single empirical equation could be found to represent these data, although they appear to be in the nature of charging currents rather than ion currents. For somewhat higher applied fields the current is observed to decrease initially, reach a minimum, and then increase approaching ultimately the steady-state ion current for the applied field strength. These data can be accounted for satisfactorily by only the polarization theory of ionic current transients.
