Definitions
- the present invention relates to a process for producing protective layers of silicides and / or oxidized silicides on a substrate in which silicide or a precursor thereof is applied to the substrate and the coated substrate is subjected to a temperature treatment, a high-strength silicide coating obtained on a substrate the inventive method and the use of silicide coating.
- protective layers with comparable multifunctional properties as can be achieved with silicides are not known. These are usually thick layers well over 1000 nanometers (nm), which require long and thus uneconomical annealing times at high temperatures for the purpose of curing. When using these protective layers singular properties are used, with particular emphasis is placed on scratch resistance. For this purpose, layers are also produced and used that are based on the use of plastics and are so-called self-repairing. The lifetime of such coatings is limited. Thick layers generally have the disadvantage that they are not break-proof against bending and against temperature fluctuations. Large temperature fluctuations cause by different coefficients of expansion of the substrate and coating (bursting) of the layer.
- the present invention accordingly provides a process for the preparation of protective layers containing silicides and / or oxidized silicides on a substrate in which silicide or a precursor thereof is applied to the substrate and the coated substrate is subjected to a temperature treatment above 250 ° C without further processing.
- the resulting silicide layers show the advantageous properties of each silicide used, such as scratch resistance, abrasion, corrosion and temperature resistance up to 800 ' ⁇ - 1 .500 ° C.
- these nano-layers are predominantly semiconducting, water and dirt repellent, light-resistant, marginally light-reflecting and provide high transparency. They can be light-enhancing or -absorb Schlierend, unbreakable and also variably colored.
- some nano-silicide layers in acids and bases are stable throughout the pH range of 1-14. They also show predominantly good thermal and electrical conductivity and are impermeable to gas diffusion, in particular to oxygen, thus preventing oxidation of the substrate / support material.
- Substrate means that it can be any material in any shape, including an already formed component or workpiece, or a piece of material that is yet to be deformed, bent or otherwise machined.
- silicides or their precursors are applied by methods known to those skilled in the art, such as PVD (physical vapor deposition), CVD (chemical vapor deposition), electrostatic methods and / or screen printing.
- the silicide particles are applied by sputtering (sputtering).
- the invention includes a method for tempering and preserving surfaces that are metallic as well as non-metallic in nature. For this purpose, a nano protective layer of silicides is applied.
- Silicides are understood as meaning the pure silicides and also their oxides as well as mixtures of silicides and oxidized silicides.
- the silicides used are preferably selected from metal silicides, non-metallic silicides and / or nitro silicides of the general formulas
- Me is a boron, nitrogen or a metal and x is a number from 1 to 6 and y is a number from 1 to 4, where x and y are not integers;
- Me x Si y O z (2) wherein Me has the meaning given above and x 'is a number from 1 to 3 and y' is a number from 1 to 4, z 'is a number from 1 to 4 where x', y 'and z' are not integers have to be;
- a is a number between 1 and 2 and b is a number between 1 and 2;
- R is an organic, metallic, organometallic or inorganic radical or a mixture thereof and e is and a number from 1 to 4,

- the application of silicides different substrates / substrates results in high-strength protective layers, which surprisingly at the same time have several of the above-listed characteristic properties at layer thicknesses in the range below 1000 nm but also at very low layer thickness (10-500 nm). It can be like this multifunctional nano-layers are produced, which result in moderate production costs (coating and curing process) due to the low layer thicknesses applied.
- the characteristic properties of the nano-silicide layers are obtained by treatment at high temperatures, also called annealing, usually above 250 ° C. The annealing is preferably carried out at temperatures between 250 ⁇ and 1, 000 ° C.
- the temperature should be adjusted to the temperature resistance of the substrate to be coated, the temperature treatment for substrates made of plastic materials preferably at temperatures of 250 ⁇ to 600 ' ⁇ and for substrates made of metal or high temperature resistant andren materials above 750 ° C.
- the tempering takes place according to the invention immediately after the coating, ie without the fresh coating being subjected to further process steps. This process step is preferably carried out with exclusion of oxygen and addition of inert gases.
- the silicides are mainly easily oxidized, this is especially true for the silicides after coating by PVD and electrostatic coating, since they arise in amorphous form. Even in the presence of small amounts of oxygen, especially in contact with air, oxidized silicides are formed. The formation of such oxides is in part desirable, thus forming passivated silicide oxide layers. A coating containing a small amount of oxidized silicides can also be obtained if already partially oxidized silicides are used for the coating.
- Annealing is performed for a period of time until the coating has fully cured, usually from one minute to 60 minutes, preferably from 5 minutes to 45 minutes. Subsequently, the coated substrate is allowed to cool to room temperature. Usually, the cooling takes place under inert gas. The cooling is preferably carried out slowly, in order to avoid creating stresses in the substrate due to a rapid temperature change. The temperature profile during cooling is preferably matched to the temperature behavior of the coated substrate.
- the inert gas is completely or partially replaced by air. In this way, a partially oxidized coating can be obtained.
- the passivated silicide oxide layers thus generated have a layer thickness of a few nanometers.
- the aforementioned properties can be used as a coating on polymeric materials such as plastics, on glasses or glass-like materials, as well as metals and ceramics.
- the substrate is selected from silicate-containing materials such as glass, glass-like materials, ceramics, gemstones, metals, including precious metals and transition metals, metal oxides, plastics, and also graphite and similar materials.
- the substrate and the deposited silicide are aligned so that the substrate and silicide contain identical elements. If, for example, a metal A is coated as the substrate, the silicide used is preferably a silicide of A or a precursor thereof, or if a mixture of silicides is used, a certain proportion is the silicide of A.
- silicon carbide and silicon nitride or a mixture with silicon carbide and silicon nitride has proven to be a very suitable coating agent.
- the adhesion of the coating according to the invention can be improved if intermediate layers of a metal, such as aluminum or a transition metal with a layer thickness between 5 and 20 nm, preferably between 5 and 10 nm are applied.
- a metal such as aluminum or a transition metal with a layer thickness between 5 and 20 nm, preferably between 5 and 10 nm are applied.
- chromium, titanium, aluminum and other metals as well as transition metals have proven suitable.
- the application of the intermediate layer has proven to be suitable in particular in the coating of plastics.
- silicide layers at low layer thickness below 1000 nm have not been used for practical use.
- silicides for the above-described coatings and applications can be used individually or in combinations of two or more silicides and their oxides, as well as non-silicidic layers.
- This new technology based on nano-silicide coatings can, for example, find the following applications: novel heating systems, aviation and vehicle technology, in the optical and metallurgical field for the production of corrosion-resistant and scratch-resistant surfaces, as well as in connection with precious metals to reduce / avoid oxidation and wear of the surface or for the coating of materials for electrolysis and similar processes (Example: electrodes for the electrochemical cleavage of water with light to hydrogen and oxygen and for fuel cell technology).
- nano-silicide coatings for reflective materials such as (solar) mirrors and reflectors are possible.
- Another object of the present invention is a substrate having a high-strength silicide coating obtained by coating a substrate with a silicide or a precursor thereof according to the method of the present invention.

This results in multifunctional nano-coatings which predominantly have the characteristic properties mentioned above on page 2 at the same time.
- Example 1 A copper plate is coated with copper silicide (CuSi as target).
- the copper plate is first cleaned with isopropanol, so that the ions of sputtered copper silicide to the copper and not to foreign particles dock.
- the copper silicide layer sputtered in the range of 30 - 50 nm (nano-layer, sputtering time 3 minutes) makes the surface of the copper plate scratch-resistant, oxidation-resistant and dirt and water-repellent without losing its electrical conductivity.
- PVD coating pulsed electrostatic coating technology can be used.
- Example 2 Glass plates (window glass and quartz glass) are coated with silicon carbide (SiC as target) For this purpose, the glass plates are cleaned in advance with isopropanol and toluene, so that the sputtered silicon carbide does not bind to foreign particles. With the silicon carbide sputtered in the range of 20 - 40 nm, the surface of the glass plate becomes scratch-resistant and at the same time absorbs the incident light up to 80 - 90% depending on the layer thickness (measurements by means of a connected measuring device).

- Example 3 Was carried out analogously to Example 2, but the glass surface is coated with silicon nitride (eg N 4 Si 3 ) and silicon carbide (SiC), both in each case as a target present and alternately in combination. As a result, a higher light transparency is achieved, compared with Example 2, which uses exclusively SiC. If silicon nitride is used exclusively for coating, a highly transparent and colorless nano-layer (layer thickness 40-60 nm) with the characteristic features mentioned is produced after annealing at 840 ° C. and slow cooling.

No wear of the electrode was observed for months, using electrolyte solutions in the range of pH 1-14.
- electrode materials such as titanium and graphite were coated with SiC and silicon nitride (eg 200-300 nm layer thickness) and used for the photoelectrolytic cleavage of water to hydrogen and oxygen as electrodes. No wear of the electrode was observed for months, using electrolyte solutions in the range of pH 1-14.
