    摘要： Disclosed is an electrolyte for micro-arc oxidation, which includes silicate, a fluoride, an alkali metal hydroxide, a pore modifier selected from at least one of triethanolamine and diethanolamine, and a polar solvent. Also disclosed is a method for dyeing a substrate which includes immersing a metal substrate as an anode into the electrolyte, oxidizing the substrate to form an oxide layer on the substrate, applying a solution containing a dye on the oxide layer, and allowing the dye to adhere on the oxide layer, so as to obtain a half-finished product, and forming a sealing layer on the half-finished product.

    摘要： A composite structure includes a passivated substrate, a sealing layer, a conductive layer, and a coating layer. The passivated substrate includes a substrate body made of a metallic material that is magnesium or magnesium alloy, and a porous passivation layer which is disposed on the substrate body, and which is made of an oxide of the metallic material. The sealing layer is disposed on the porous passivation layer, and is made of a sealing material. The conductive layer is disposed on the sealing layer, and is made of an electrically conductive material. The coating layer covers the conductive layer, and includes an electrophoretic material and/or a metal. A method of making the composite structure is also disclosed.

    摘要： Anodic oxide coatings that provide corrosion resistance to parts having protruding features, such as edges, corners and convex-shaped features, are described. According to some embodiments, the anodic oxide coatings include an inner porous layer and an outer porous layer. The inner layer is adjacent to an underlying metal substrate and is formed under compressive stress anodizing conditions that allow the inner porous layer to be formed generally crack-free. In this way, the inner porous layer acts as a barrier that prevents water or other corrosion-inducing agents from reaching the underlying metal substrate. The outer porous layer can be thicker and harder than the inner porous layer, thereby increasing the overall hardness of the anodic oxide coating.

    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.
