    摘要: An object of the present invention is to provide a method for preparing a plating solution for aluminum electroplating useful for the production of a high-ductility, high-purity aluminum foil at a high film formation rate, etc., which is an easy-to-handle plating solution that does not solidify and allows for an electroplating treatment even at 25° C. The present invention as a means for achieving the object is characterized in that in a preparation of a plating solution containing at least (1) a dialkyl sulfone, (2) an aluminum halide, and (3) a nitrogen-containing compound, the blending proportions of the dialkyl sulfone, the aluminum halide, and the nitrogen-containing compound are such that per 10 mol of the dialkyl sulfone, the aluminum halide is 3.5+n to 4.2+n mol, and the nitrogen-containing compound is n mol (wherein n is 0.001 to 2.0 mol). In addition, a plating solution for aluminum electroplating prepared by the method of the present invention allows for an electroplating treatment with high aluminum deposition efficiency relative to the current flow, and is thus advantageous in that electricity usage can be reduced, resulting in excellent economic efficiency.

    摘要: In a plating bath for electrodeposition of aluminum, comprising a nonaqueous electrolyte using a eutectic mixture fusible at room temperature, the plating bath comprises a mixture of about 40 to 80 mol % of an aluminum halide and about 20 to 60 mol % of butyl pyridinium halide, or further comprises an organic solvent mixed in said mixture. This plating bath may not cause any color change of a coating into gray or black to assure white and uniform appearance, even when current density is increased to 30 A/dm.sup.2 or varied in the range from 0.1 to 30 A/dm.sup.2.

    摘要: An electrolytic bath for coating articles of aluminum and its alloys consists essentially of an aqueous solution containing an alkali metal silicate, a peroxide, a water-soluble carboxylic group-containing organic acid and a water-soluble fluoride. A vanadium compound may also be included in the bath whenever the coated articles are intended to be used for decorative purposes. In the process, the aluminum article is immersed in the bath and a voltage shock is applied thereto by imposing a voltage potential between the aluminum metal serving as the anode and a cathode immersed in the bath. The voltage potential is quickly raised to about 300 volts within about 2 to about 10 seconds and thereafter, the voltage is increased gradually to about 450 volts within a few minutes until the desired coating thickness is formed.
