Abstract:
A method of anodizing an anode comprising anodizing at a temperature of about 60Â° C. to about 125Â° C. until a uniform anodic oxide film is formed over the entire anode surface with a non-aqueous electrolytic solution comprising gylcerine and at least one soluble salt formed by the neutralization of at least one non-halogen-containing organic or inorganic acid anion with at least one alkali metal, ammonium, or protonated amine cation; wherein the acid anion is derived from an acid having a pKa lower than phosphoric acid; and wherein the anode comprises a valve metal-derived nitride, sub-nitride, oxide, or sub-oxide, or an alloy thereof, a mixture thereof, or a metallic glass composition thereof.
