The effects are evaluated for systematic variations in high voltage anodization process parameters including electrolyte temperature, resistivity, and anodic current density. Samples of two types of aluminum alloy; 1100, and 6061-T6, with two types of surface texture, were anodized. The electrolyte consisted of a non-aqueous solution of ammonium tartrate and ethanol. Properties of the resultant coatings evaluated included anodic oxide growth rate, thickness, density, morphology, entrained impurities, capacitance, dissipation factor, breakdown strength, defect probability, and leakage current.
