Definitions
- the invention relates to a device with a scratch-resistant technical surface that has optimized wetting properties and a related method for producing the device.
- Devices of the aforementioned type are used in a wide variety of technical fields in which the technical function of the surface of a body or a component is of particular importance.
- surfaces that serve to protect against all types of media such as covers, optical viewing and protective windows, etc., should have a high level of mechanical robustness on the one hand in order to withstand external mechanical impacts on the surface with as little wear as possible, and on the other hand in to have as little contact as possible with a medium occurring on the respective surface in order to avoid the technical functionality of the surface being affected by wetting with a medium.
- the surface has dirt and fluid repellent properties.
- the device according to the invention described below and the method suitable for producing the device see surfaces with mechanically robust, ie. H. scratch-resistant, properties and with specifically optimized wetting properties which, depending on the intended use, are characterized either by the lowest possible degree of wetting or by the best possible wettability with media, in particular liquids and fluids.
- the further explanations deal primarily with technical surfaces which have the lowest possible wetting properties.
- layer materials are applied to the surfaces to be protected in a manner known per se, which primarily serve as protection against external mechanical influences in the form of hard material layers.
- hard material layers have a high abrasion resistance, they often also have high surface energies due to their binding type, which in particular increases lead to an increased adherence of solid or liquid media, whereby the surfaces of such hard material layers easily become dirty.
- Organic or biological materials in particular, which themselves have low surface tensions, are able to adhere permanently to the hard material surface with intimate contact.
- Measures to reduce the adherence of the above materials consist in applying substances to the surface which themselves have only low surface energies.
- substances are, for example, fluorine- or alkyl-substituted organic building blocks and / or polymers, through which the surface of the hard material layer can be passivated with regard to its wettability.
- the invention is based on the object of designing a device with a scratch-resistant technical surface which has optimized wetting properties in such a way that the surface in question should have both a high scratch resistance and a sufficiently wetting-optimized function with high long-term stability.
- a device with a scratch-resistant technical surface that has optimized wetting properties is developed in such a way that the technical surface has structurally distributed structural elements with structural dimensions in the ⁇ m and / or sub- ⁇ m range that extend laterally and normally to the surface, and that at least or only surface areas between two adjacent structural element maxima are at least partially covered with a material layer influencing the wetting properties.
- the idea on which the invention is based lies in the interaction of the structural elements, which preferably consist of mechanically robust hard material, the structural maxima of which protrude above the material layer located in the recesses of the microstructure, and precisely the material layer itself which determines the wetting properties of the surface.
- the structural elements which elevate the material layer serve primarily for protection before direct frictional contact with the material layer with possible friction partners.
- the structural elements ensure a safe spacing of the friction partners from the material layer located in the recesses of the microstructure. In these cases, only the upper areas of the structural elements come into contact with a respective friction partner, which however makes the structural elements extremely resistant to damage due to their mechanical robustness and hardness.
- the selected hardness of the material from which the structural elements are made is therefore decisive for the scratch resistance required by the surface.
- Structural elements with lateral structural dimensions between 50 nm and 150 ⁇ m and with vertical ones have proven particularly advantageous with regard to a desired high scratch resistance in combination with optimized wettability Dimensions, ie structure dimensions oriented normal to the surface, in the range between 20 nm and 150 ⁇ m.
- the microstructured technical surface is incorporated directly into the material surface of a body or a component.
- the microstructuring is advantageously carried out with the aid of shaping embossing tools with which the surface of the respective device or component is processed.
- the structural elements forming the microstructure are produced using a shaping embossing tool which has the negative shape of the microstructure and which is pressed under pressure onto the surface of the component to be machined.
- the pre-structured surface can be covered over the entire area with a suitably selected material layer.
- known deposition techniques are available, such as, for example, wetting the pre-structured surface by means of immersion technology, applying the material layer by means of mechanical application techniques, for example using brush or stamp technology, spinning, spraying, vapor deposition or plasma-assisted application , Any combinations of the above coating techniques are also possible.
- the material layer influencing the wetting properties is deposited with a layer thickness on the pre-structured surface, in which all structure element maxima are preferably covered with a uniform material layer thickness.
- the material layer thickness exceeding the structure element maxima should preferably not exceed 0.5 mm. Since, as will be explained further below, the material determining the wetting properties has a far lower mechanical robustness or strength than the material from which the structural element is made, as a rule there is material removal due to the intended use and use of the respective component, through which the material layer applied to the microstructure is removed to a material residual layer thickness which is in the range of the maximum structural element height and below.
- a further material removal on the material layer caused by external influences does not take place even under abrasive environmental conditions, especially since the material layer located in the intermediate areas between the structural elements is protected from further material removal by the structural elevations.
- a technically controlled material removal process can also be carried out after the material separation process in order to obtain the desired material layer deposition between the structure element maxima.
- the choice of material for the material layer to be deposited between the individual structural elements plays a central role. If, as mentioned at the beginning, it is necessary to create a scratch-resistant surface on which, for example, liquids or fluids should show the tendency of spreading, materials should be selected on which liquids or fluids have a very small contact angle, preferably a contact angle of 0 ° , ie the liquid or fluid drop spreads as a thin film over the entire surface. On the other hand, if the surface should have the lowest possible wettability with liquids or fluids, materials should be selected for the material layer which, when in contact with liquids, produce the largest possible contact angle, preferably> 90 °.
- Such material layer surfaces have a highly hydrophobic or material or dirt-repellent effect.
- Such materials are preferably molecules, molecular building blocks or polymer building blocks which are formed at least in part by molecules carrying fluorine, silane and / or alkyl groups.
- Molecules, molecular building blocks or polymer building blocks which at least partially contain fluorine compounds, such as, for example, fluorosilanes, fluorosilane hydrosilates, fluorocarbon resins or fluoroacrylates, are particularly suitable for this purpose. Materials with silicone-based components are equally suitable.
- suitable groups of substances relate to organic oligomers, polymers or copolymers with polar groups, such as, for example, hydroxyethyl acrylate, hydroxyethyl methacrylate, polyurethane, polyethylene glycol or hydroxyethyl cellulose.
- polar groups such as, for example, hydroxyethyl acrylate, hydroxyethyl methacrylate, polyurethane, polyethylene glycol or hydroxyethyl cellulose.
- suitable materials can be continued in a manner known per se.
- the materials which control the wetting or influence the wetting properties can at least partially contain metals or metal ions, for example silver or copper, in order to achieve a bacterial, antibacterial and cell-active action.
- a suitable material layer thickness of the material layer to be arranged in the depressions of the microstructure to form about 30 or more molecular layers from the molecules, molecular building blocks and / or polymer building blocks described above.
- the microstructure described above has been incorporated into the material surface of a component or device by means of molding or embossing technology, so that the individual structural elements consist of the same material as the component itself or parts of the component itself.
- the PVD deposition method with which hard material layers are to be deposited on a component surface is particularly suitable for this purpose, the structural elements being able to form in a self-organizing manner.
- Hard material layer materials Me: O x / N y , using one of the following metals Ti, Zr, Al, W, Mo, Si, Cr.
- Such hard materials have the material hardness required for the desired scratch resistance and are able to permanently protect the material layer influencing the wetting properties from external mechanical and abrasive influences.
- a surface structure according to the invention with a structured base substrate which is designed in the manner of a film, the top surface of which is microstructured in the manner described above. At least in the depressions delimited by adjacent structural elements, a material layer determining the wetting properties is deposited, the layer surface of which is in each case at least surmounted by the highest elevations of the structural elements.
- the film-like base substrate can accordingly be applied to any components and device via an adhesive layer provided on the surface opposite the structured surface.
- suitably made-up foils that have optically transparent properties can be glued to window panes, which gives the window surfaces, which are particularly exposed to external weather, a scratch-resistant, water- and dirt-resistant surface effect.
- Fig. 2 component with additional microstructured PVD layer. WAYS OF IMPLEMENTING THE INVENTION, INDUSTRIAL APPLICABILITY
- FIGS. 1a and b each show schematic cross-sectional images through the surface area of a component 3, which is preferably made of a hard material that has sufficient material hardness.
- the surface of component 3 has a microstructuring with stochastically designed and arranged structural elements 1.
- a periodic arrangement of structural elements or a mixture of stochastically and periodically arranged structural elements 1 is also conceivable.
- the structural elements 1 each have lateral distances between 50 nm-150 ⁇ m.
- Average vertical structure dimensions are in the range between 20 nm and 100 ⁇ m.
- Known embossing and molding processes can be used to produce the microstructure introduced into the surface of component 3, for example by means of press contact between an embossing tool or stamp and the material surface to be structured.
- the technically functional surface has a material layer 7 which determines the wetting properties and which in the exemplary embodiment shown according to FIG. 1a completely covers the structural elements 1.
- the overlap stems from the way in which they are produced, in which the material layer 7 is deposited onto the pre-structured surface by means of a conventional material application process.
- Mechanical application techniques are suitable, for example, using a brush or wetting the microstructured surface by immersing the microstructure in an immersion bath, and the material layer 7 can also be deposited by means of spinning, spraying, vapor deposition or by means of plasma-assisted application.
- materials for the layer 7 are selected which have certain surface energies and either lead to the spreading of liquids or fluids coming into contact on the material layer surface 7 or to their corresponding rejection.
- the latter property serves especially for technically functional surfaces with dirt and water repellent surface properties.
- Materials known per se to those skilled in the art are available for selecting suitable materials, as mentioned above.
- the material layer 7 is far less mechanically robust than the material from which the component 3 is made, so that external mechanical effects, for example due to friction, result in a corresponding removal of material from the material layer regions projecting beyond the structural elements 1.
- the intended use of the surface designed according to the invention leads to material removal up to a state which is shown in FIG. 1b. Material removal can also be carried out in a technically targeted manner
- the material layer 7 is reduced in thickness by appropriate material removal so that the material layer 7 covers only those surface areas which are each between two structure element maxima.
- the structural element maxima which rise vertically above the areas of the material layer 7 located within the depressions, serve on the one hand to protect against further material abrasion due to abrasion on the material layer 7 and, moreover, give the entire surface its scratch resistance, especially since they preferably consist of hard material, such as from nitridic or oxidic hard materials.
- the material layer regions 7 located between the individual structure element maxima determine the wetting properties of the structured surface.
- FIG. 2 shows a further alternative exemplary embodiment, in which the microstructured surface is not worked directly into the surface of a material component 3 as in the exemplary embodiment shown above, but is deposited in the form of an additional PVD layer 8 on a surface of component 3.
- self-organizing structure formation is advantageously used, which can be produced in the context of the PVD deposition process.
- the structural elements 1 are stochastically designed and distributed.
- the material layer 7, which determines the wetting properties, is deposited in the recesses between the structural element 1 projecting above the surface, as described above.
- nitridic and / or oxidic hard materials according to the following material structure occurs to form the structural elements: Me: O x / N y with the metals titanium, zirconium, aluminum, tungsten, molybdenum, silicon or chromium.
