Thin oxide films were prepared electrochemically on the aluminum surface using the high-voltage discharge and potentiostaticmethods in deionized water as an electrolyte. The growth of continuous films occurred only at potentials lower than the breakdownpotential. The films obtained by the discharge method are more uniform and can grow to a higher thickness in comparison tothose formed by the potentiostatic mode, as demonstrated by electrochemical impedance spectroscopy (EIS), transmission electronmicroscopy (TEM), and scanning Kelvin probe force microscopy (SKPFM). The data herein obtained can be used as a reference tounderstand better the properties of the films produced in conventional electrolytes where apart from water other species are present
