Definitions
- the invention relates to a method for coating motor vehicle rims, in particular made of light metal, in which the rim is first provided with a primer made of powder or wet paint to compensate for the unevenness and the primer is coated with a galvanizable layer which is then galvanically chrome-plated.
- the conditioning of the galvano-ABS plastic layer is particularly labor-intensive and generates considerable amounts of waste water and waste solutions, the discharge or treatment and recycling of which is problematic in accordance with the provisions of the Closed Substance Cycle and Waste Management Act.
- the coating produced in this way is clearly cheaper than the chrome plating of the type mentioned at the outset, in particular because it does not require the expensive galvanizable plastic coating from a conductive galvano-ABS plastic and its conditioning. But this coating, which imitates a real chrome plating, never achieves the wear resistance and the shine of a real chrome plating with an outer skin made of metallic chrome.
- the invention relates to a method for coating motor vehicle rims, in particular made of light metal, in which the rim is first provided with a primer made of powder or wet paint to compensate for the unevenness and the primer is coated with a galvanizable layer which is then galvanically chrome-plated, whereby this Process characterized in that the galvanizable layer is a metal layer which is applied to the primer by physical deposition of metal from the gas phase (PVD) or by thermal spraying.
- PVD gas phase
- the pretreatment of the rims by polishing and removing the adhering oxides which is necessary for the direct chrome plating of motor vehicle rims, is largely eliminated.
- the primer is applied in such a thickness that it compensates for unevenness and creates a completely smooth surface that adheres very firmly to the rim, especially when it is burned in.
- the subsequent coating with metal by deposition of the metal from the gas phase (PVD) or by thermal spraying also requires relatively little effort.
- PVD Physical Vapor Deposition
- PVD Physical Vapor Deposition
- the surface of the deposited metal layer is particularly smooth and does not need to be polished or otherwise treated.
- this electrically conductive metal layer is electroplated using conventional techniques.
- the electrically conductive layer made of metal used in the method according to the invention is considerably less expensive than the previously used layer made of galvano-ABS plastic. Above all, the process of galvanizing the metal layer is much easier than a surface made of galvano-ABS plastic, because the complicated and costly conditioning of the surface explained above is eliminated.
- Another significant advantage is that the method according to the Coating produced according to the invention has a very good temperature resistance.
- the metal layer applied to the primer suitably consists of copper. Copper has the property of conducting electrical current particularly well and evenly and is therefore particularly well suited for the subsequent electroplating.
- the motor vehicle rim is designated by reference number 1.
- This motor vehicle rim 1 is first pre-cleaned in a pre-cleaning 2 in order to be freed of adhering contaminants, dirt, grease, chips, etc. From the pre-cleaning 2, the rim 1 then passes into a coating system in which the rim is coated with a primer (powder coating or wet coating). This coating is then baked in a kiln 4. Then the rim gets into one
- Coating station 5 in which it with a deposited from the gas phase metal layer, for. B. of copper is vaporized. The through the
- Evaporation layer adheres firmly to the primer and is suitable for the subsequent electroplating with conventional electroplating processes. Evaporation takes place by physical deposition of the metal from the gas phase (PVD) or by thermal spraying.
- PVD gas phase
- the rim 1 provided with the vapor-deposited metal layer reaches three successive electroplating baths 6, 7, 8, in which the metal layer is successively coated with nickel in the electroplating bath 6, with bright nickel in the electroplating bath 7 and with chrome in the electroplating bath 8.
- the finished chromed rim 1 ' is carried out at the end of the process.
