摘要: An electrolytic process, an electrolytic solution and electrolytic assembly are disclosed, for anodizing in one main step non-ferrous metallic parts, or their alloys to form a uniform coating. The electrolytic solution is free of toxic or harmful chemicals. Examples of treatable metals include aluminum, cast aluminum, magnesium, hafnium, tantalum, titanium, vanadium, and zirconium. The treatment is a one-step process since the cleaning and coating of the nonferrous metals are performed in the same electrolytic cell or tank and solution, preferably using the same electrical device for both actions. No preliminary steps like degreasing, de-smutting or activation are needed due to the absence of toxic acids or salts in the process. The process is therefore eco-friendly, easy to perform and provides excellent results. The non-ferrous metallic parts once coated can be used in the automotive or aircraft industries.
