Embodiment Construction

[0017] The invention is illustrated with the aid of examples and figures. The drawing shows a cross-section of an aluminum automotive part, for example a trim strip 1 . The surface of the decorative strip 1 is treated with aluminum anodic oxidation. In this case, colorless or colored aluminum anodizing can be specified. In particular, a certain surface roughness can be provided by the type and duration of the anodization of the aluminum. After anodizing the aluminum, the sol-gel coating is applied to the decorative strip 1 by spraying, rolling, dipping, scraping and / or rolling and hardens by a heating process. The sol-gel coating 2 is non-flammable as well as heat and fire resistant. from the coating when burning No gas is formed on departure. The coating material preferably comprises only inorganic components. Alternatively, organic components may also be included. In addition, combinations of inorganic components and organic components are also possible.

Abstract

The invention relates to a vehicle component made from aluminum or aluminum alloy through aluminum anode oxidation treatment, particularly additional component of vehicles, preferably outside component of vehicles, preferably decorating parts of vehicles particularly. The component is provided with a sol-gel coat (2) at least partly. Besides, the invention further relates to vehicles with corresponding vehicle components.

Description

technical field [0001] The invention relates to a vehicle component made of anodized aluminum or an aluminum alloy, in particular a vehicle accessory, preferably an exterior vehicle part, particularly preferably a vehicle trim. Background technique [0002] Existing aluminum automotive components are polished or aluminum anodized. These components are subjected to mechanical and chemical loads. For example, such parts come into contact with cleaning agents when washing cars. If the cleaning agents used are aggressive, this can lead to visible damage to the surface of the vehicle components. Contents of the invention [0003] It is therefore the object of the present invention to provide a motor vehicle component whose surface is more durable against environmental influences and other loads, especially acids, alkalis and solvents. [0004] According to the invention, this object is achieved in that the component, in particular after the aluminum anodizing process (at lea...
