Abstract
Bode diagrams for aluminum PC (abbreviated from pulse current) oxide films were first obtained by AC impedance measurements in a wide range of frequency.The experimental results show that different kinds of electrical equivalent circuits can be used for representing PC films and DC (abbreviated from direct current) oxide films separately,the main differences between them are their porous layers,the PC films are more even with little defects.Those are also verified by SEM and V I characteristic curve measurements.
