    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.

    摘要： This application relates to a part that includes a metal oxide layer having pore structures. In some embodiments, dye molecules having aromatic rings can be disposed within at least one of the pore structures. Additionally, the at least one pore structures can include dispersion molecules, where the dispersion molecules form non-covalent interactions with the dye molecules. By forming non-covalent interactions between the dye molecules and the dispersion molecules, the aromatic rings of the dye molecules are prevented from forming other non-covalent interactions with other dye molecules. Additionally, techniques for chemically stabilizing the color dye bath for dyeing anodized parts are also described.

    摘要： A method for dye-free coloring of one-time anodic aluminum oxide surface is revealed. First provide a substrate containing aluminum. The substrate containing aluminum is anodized once at room temperature. The anodizing process includes a step of applying a pulse signal on the substrate containing aluminum for a first period of time. Thus a porous aluminum oxide layer is formed on surface of the substrate containing aluminum. The pulse signal includes a part with positive voltage and a part with negative voltage. Then a metal layer is deposited on the surface of the porous aluminum oxide layer. The porous aluminum oxide layer has a first interference wavelength. Next perform a linear regression of the first interference wavelength versus the first period of time. The absolute value of the slope of the regression line obtained ranges from 1.8 to 38.5. The absolute value is positively correlated with the positive voltage.
