Abstract

The invention discloses aluminum alloy with a plasma micro-arc oxidation color film. The aluminum alloy with the plasma micro-arc oxidation color film is prepared by carrying out plasma micro-arc oxidation treatment on the aluminum alloy, and the oxidation liquid in the plasma micro-arc oxidation treatment contains a samarium salt solution. The aluminum alloy with the plasma micro-arc oxidation color film has outstanding metal performance, and good light resistance, heat resistance, corrosion resistance and abrasive resistance, and adopts a film formed by plasma micro-arc oxidation technology.Hand feeling is fine, and metal texture is strong. In the manufacturing process of the aluminum alloy, a colored samarium salt solution is adopted as the oxidation solution, and the plasma micro-arcoxidation technology is adopted for preparation, oxidizing and coloring processes, so that dye dyeing is not needed and the aluminum alloy is environment-friendly.

Description

Technical field [0001] The invention relates to an aluminum alloy with a plasma micro-arc oxidation color film, in particular to the application of the aluminum alloy with a plasma micro-arc oxidation color film in electronic products, especially as a metal body of a mobile phone. Background technique [0002] Plasma micro-arc oxidation, abbreviated as micro-arc oxidation, is a technology to treat the surface of materials. It places non-ferrous metals such as magnesium, aluminum, and titanium in an electrolyte. Under the action of a strong electric field, the gas in the solution is ionized and the metal Surface oxidation produces plasma, which causes micro-zone spark discharge spots on the surface of the substrate. Under the combined action of a series of complex reactions such as thermochemistry, plasma chemistry, electrochemistry, diffusion reaction, and high-temperature phase change, a ceramic oxide film is prepared. [0003] As a lightweight material with unique properties, alu...
