Definitions
- the invention relates to durable and dirt-repellent aluminum-based gloss coatings on motor vehicle wheels, motor vehicle rims and methods for producing such gloss layers on light-metal or steel substrates.
- high-gloss surfaces can also be achieved through the process of so-called "gloss-anodising" of the aluminum surfaces.
- Such a method for aluminum wheels is known, for example, from Alcoa under the Dura-Bright® brand.
- the main steps of the process include applying a chemical whitening composition to the product, deoxidizing the product surface, electrochemically generating a porous oxide on that product surface by contacting it with an electrolyte bath, containing phosphorous or phosphonic acid and applying a silicate or siloxane-based outer layer to the porous oxide.
- the surface is dirt-repellent and scratch-resistant as possible.
- ETC coatings Dirt-repellent coatings or so-called easy-to-clean coatings or coatings (ETC coatings) are known for the protection of high-quality components made of glass, plastic and metals and are intended to prevent contamination or facilitate cleaning. The mechanism of action varies depending on the application.
- water-repellent coatings are used for glass surfaces. Clean glass is relatively hydrophilic and forms a contact angle of 20 ° to water. In contrast, a hydrophobic ETC coating increases the Contact angle to well over 100 ° with respect to water. This ETC coating offers a significantly reduced wettability, so that waterborne soiling can bead off or be easily washed off.
- WO2005 085 374 A1 discloses particularly scratch-resistant coatings for light-alloy rims which are based on perhydrosilazanes. Scratch-resistant and dirt-repellent layers are known, for example, from WO 02088269 A1 or DE 10 2004 001 288 A1. The latter document describes hydrophilic coatings for surfaces containing one or more polysilazanes and an ionic reagent or mixtures of ionic reagents.
- the ionic reagent is preferably a salt of a carboxylic acid, especially a hydroxy carboxylic acid, or a cationic or anionic silane, or an oligomer or polymer. This The effect of the hydrophilic layers is based on the fact that hydrophobic contaminants adhere poorly or that the surface can be washed off well with aqueous cleaning agents.
- the object of the invention is achieved in a first aspect, by a surface coating on motor vehicle wheels of light metal casting alloys or steel, which may comprise several layers, wherein it has at least one directly applied to the wheel surface first layer of a CVD coating of aluminum or aluminum alloy, with the features of claim 1.
- the invention is achieved by a process for producing a durable glossy coating on aluminum or steel surfaces comprising the steps
- An advantage of the invention is that the visual appearance of expensive forged aluminum rims is thus possible cost-effectively even with low-cost cast aluminum rims or even on steel rims. Due to the nature of the gloss coating made of Al or Al alloy, no high demands must be placed on the alloys used as substrate. The use of light metal alloys, Al cast alloys or steel is not difficult. The selected alloys need no longer be accessible to a gloss anodization, since the Al or Al alloy layer unfolds the gloss effect.
- the thickness of the first layer is preferably 10 to 500 ⁇ m. Particularly preferably, the thickness of cast aluminum rims or steel rims is 30 to 100 ⁇ m.
- the first layer of Al or Al alloy is often not durable enough.
- the surface of the first layer therefore carries a second layer in the form of an electrochemically generated micro- or nano-porous oxide layer.
- This coating is a coating comparable to the anodization of aluminum surfaces.
- the metallic surface is passivated by the firmly adhering oxide layer and protected against further corrosive attack.
- this layer forms a good primer for further organic coatings.
- the thickness of the oxide layer must be limited so that the gloss of the surface is not lost.
- This second layer preferably has a thickness in the range of 50 to 1000 nm.
- the first or the second layer thus carries a third layer of a final lacquer layer, in particular a clearcoat or an easy-to-clean lacquer (ETC lacquer).
- ETC lacquer easy-to-clean lacquer
- the combination with an ETC coating achieves a visually high-quality surface with the highest corrosion protection and lasting shine at the same time.
- An optional ETC coating for example with organosilicates, can effectively combat the problem of brake dust rim contamination.
- the ETC coating can be hydrophilic or hydrophobic coatings. The optimal choice depends, among other things, on the choice of brake lining material in the vehicle brake.
- the third layer is formed predominantly of silane, silazane, siloxane and / or silicone polymers.
- the components form the main component of the coating.
- Other components may in particular be the scratch-resistant filler, hydrophobic or hydrophobizing additives or catalytically active additives.
- Silica powder, clay minerals, alumina nanopowders or SiO 2 nanofillers are of particular importance as fillers.
- As catalytically active In particular, titanium oxide is important as an additive, which acts oxidatively on the superficially deposited dirt particles by the action of UV light. Particularly favorable is the combination of hydrophilizing additives and catalytically active titanium oxide.
- a suitable third coating is further composed of siloxane with silicate fillers.
- the third layer comprises perhyrdosilazane polymers as the main constituent and hydrophilic (co) polymers and / or additives as additives.
- perhyrdosilazane polymers as the main constituent
- hydrophilic (co) polymers and / or additives as additives.
- a combination of perhyrdosilazane polymers, hydrophilic (co) polymers and catalytically active titanium oxide proves to be a particularly effective, scratch-resistant and dirt-repellent coating or easy-to-clean lacquer on the glossy layer or the bright anodised gloss layer.
- the surface coating of 1, 2 or 3 layers is applied to a motor vehicle wheel made of an Al casting alloy with an Si content in the range from 3 to 12% by weight.
- Another aspect of the invention is a method for producing a durable glossy coating on aluminum alloy or steel surfaces, which comprises as essential steps:
- the vapor deposition By the vapor deposition, the formation of a homogeneous well-adhering gloss coating on a variety of Al or steel alloys is possible.
- the subsequent electrochemical oxidation increases the corrosion resistance of the surface and improves the surface finish for a subsequent coating.
- vapor deposition which is preferably carried out as a CVD or PVD process (chemical vapor deposition or physical vapor deposition)
- a pure aluminum layer in a thickness of from 10 to 300 ⁇ m.
- a cold gas process is preferably used, in particular in the deposition on light metal substrates or aluminum wheels.
- the aluminum surfaces are brought to a temperature in the range of 280 to 350 0 C and the steel surfaces to a temperature in the range of 280 to 580 0 C for deposition.
- the cold gas process is characterized in that the carrier gas loaded with the gaseous Al carrier substances has a lower temperature than the substrate to be coated. In particular, the carrier gas temperature is significantly below the decomposition or deposition temperature of the Al carrier substance.
- Particularly preferred is an all-round coating of a cast aluminum rim or steel rim with an applied by a low-temperature CVD method pure aluminum layer in a layer thickness of 30 to max. 100 ⁇ m performed.
- the implementation of the particularly suitable CVD methods is already known in principle and described for example in WO 2005 028 704 A1.
- the second layer of alumina is preferably prepared so that the gloss layer is deposited from deposited Al or Al alloy.
- the anodization parameters are adjusted to form nano or microstructures of columnar alumina. Due to the interspaces of adjacent columns, the layer is constructed as such nano- or microporous.
- a clear coat or an easy-to-clean coating is applied to the first coat, but especially to the second coat.
- the job can be done by wet or powder coating.
- the method is particularly suitable for coating Al cast alloy wheels for passenger cars or for steel wheels for trucks or buses.
