| 摘要 |
Surface-oxidized, metallic components or semifinished products and corresponding planar components and methods for producing such components and/or semifinished products and corresponding components are disclosed. Such objects may be used, for example, in exterior skin parts of a motor vehicle, such as hoods, car roofs, car doors, fenders and/or side frames, baking trays, or baths. One object is to propose methods for producing surface-oxidized components or semifinished products that have an at least partially oxidized surface. The disclosed methods are suitable for mass production. Some example methods involve applying a surface layer comprising Al, Mg, Ti and/or Zr to a metallic substrate, and then performing plasma electrolytic oxidation of the surface layer. The metallic substrate may be cut to length and formed into a component or semifinished product before or after the plasma electrolytic oxidation. At least one part of the surface layer may be less than 200 μm. |
