Definitions
- the present invention is a composite material of a ceramic substrate with functional layers, its production and use.
- the invention also relates to transparent ceramic substrates with preferably optical functional layers.
- optical components consist of glass, glass ceramic or plastics, more rarely of monocrystalline sapphire (AI2O3 ceramic). Glasses and plastics have in common that they have low strength, temperature resistance and scratch resistance. In addition to these disadvantages, glasses have a high weight, are easily breakable and usually show a color haze. Plastics, on the other hand, have a low hardness and absorb water in part. Inorganic single crystals are involved in their production at very high cost and therefore often unprofitable.
- optical functional layers In order to improve the optical properties of the above-mentioned substrates or to fulfill a wide variety of functions, glasses, plastics, glass ceramics and single crystals can be coated with optical functional layers.
- the functional layer fulfills a tailor-made function tailored to the field of application.
- the optical layers can be deposited with different coating methods, such as deposition from the vapor phase (PVD and CVD method) and by applying liquids (sol) via, for example, sol-gel or spin-on method. It is also possible, in particular, to produce optical functional layers by means of thermal conversion (oxidation).
- the energy input is controllable and increases e.g. by higher coating temperatures or by the use of plasma or ion bombardment.
- the layer properties e.g. Layer density or layer compactness, layer adhesion or scratch resistance, positively influenced, so that consequently the highest possible energy input is desired, cf.
- layer density or layer compactness, layer adhesion or scratch resistance e.g. Layer density or layer compactness, layer adhesion or scratch resistance
- the object of the invention is therefore to provide an improved composite material of substrate and functional coating.
- a functional coating according to the invention comprises or consists of at least one functional layer, wherein the functional layer may have, for example, an optical, thermal, mechanical, chemical function or a combination of these functions.
- the functional layer may have, for example, an optical, thermal, mechanical, chemical function or a combination of these functions.
- ceramic substrates are understood in the context of this invention, in particular polycrystalline ceramics. However, monocrystalline substrates such as sapphire substrates should also be subsumed under this term.
- Ceramics other than single crystals consisting of ceramic powders in the original state, are characterized by a manufacturing process of ceramic powders, which are shaped into substrates by some kind of press or slip casting or extrusion technology and then solidified by or with sintering become.
- the ceramic substrates are at least 99 vol .-% crystalline. Glass-ceramic manufacturing processes and products are expressly excluded from this term.
- the ceramic substrate and functional coating composite presented herein may be a self-supporting, coated ceramic, or may be part of a more complex component, such as part of an architectural device, e.g. as a sight glass, his or replace parts of a bulletproof glass pane.
- ceramic substrates In contrast to known from the prior art substrates made of glass, glass ceramic or plastics, ceramic substrates have a high temperature resistance, strength and rigidity. They have a high layer stress, whereby during coating no distortion of the ceramic substrate occurs. Coatings can therefore be deposited at high temperatures and / or high energy input without adversely affecting the substrate.
- Another advantage of ceramic substrates over glass and plastic substrates is the better adhesion between substrate and coating. It is assumed that the better adhesion is based on a ceramic bond between the material partners.
- Polycrystalline ceramics have improved over single crystals, e.g. Sapphire, the advantage that they are easier to manufacture and easier to machine. They are therefore much cheaper.
- sapphire single crystals have the disadvantage of being birefringent, that is to say optically anisotropic.
- polycrystalline ceramics such as spinel are simply refractive and optically isotropic.
- the ceramic substrate and / or the functional coating and / or the composite material is transparent.
- These composite materials can be used as a replacement for all coated transparent substrates, but with the advantages described above.
- a composite material with a colorless optical functional layer having a thickness of less than 100 ⁇ , preferably less than 1 ⁇ , more preferably less than 0.5 ⁇ and most preferably less than 0.15 ⁇ , in a wavelength range of 420 to 650 nm have a fluctuation range of the RIT (real in-line transmission) of less than 10%, preferably less than 5% and particularly preferably less than 1%.
- colorless is used in the context of this invention to mean that no light is absorbed, and it is an object that is not electromagnetic Radiation in the visible, visual (VIS) region interacts.
- VIS visible, visual
- a small variation in the RIT across the surface of the coating results in a high quality functional coating.
- the composite material is colorless, it is particularly suitable for optical applications. For example, for photographic applications where natural colors are desired, an optical component having such a composite can avoid the falsification of colors.
- functional coatings which contain at least one functional layer which selects the transmission of electromagnetic waves in an absorbing, reflective or scattering manner, ie. Limits depending on the wavelength. Particularly preferably, this selection takes place in the VIS range.
- the functional coating may comprise at least one functional layer which has a reflection-reducing effect.
- reflection-reducing effect is to be understood that the composite material of ceramic substrate and functional coating has a higher RIT than the ceramic substrate without functional coating. The relationship applies:
- nsubstrate refractive index of the composite material.
- Another preferred embodiment of the invention has at least one functional layer, which has a reflection-enhancing effect, so that the composite material of ceramic substrate and functional coating has a higher reflection than the ceramic substrate without functional coating. The following relationship is fulfilled:
- R max 1 - 2 x ((n Environment “nsubstrat) / (n + nsubstrat to e g exercise))
- nsubstrate refractive index of the composite material.
- Ceramic substrates with such coatings are more or less reflective and can be used in particular for the surface design of mechanically, thermally or chemically heavily loaded parts use.
- the functional coating can also consist of a package with a plurality of functional layers, in particular selected from the functional layers described above.
- Such functional coatings can be used, for example, as multilayer antireflection layers.
- a particularly preferred embodiment of the invention is characterized in that fingerprints are little visible on the composite material.
- This can be achieved, for example, by the material composite having, as the outermost layer, a layer with a refractive index of 1.38 to 1.55, preferably 1.45 to 1.50.
- the layer refractive index is thus similar to the refractive index of lipids or skin fat.
- the methods to be used differ from methods known from the prior art in that a ceramic substrate, in particular a transparent ceramic substrate, is coated, wherein a higher energy input into the coating leads to an improved quality of the functional coating.
- the functional layers can be deposited on the ceramic substrate, for example by means of PVD, sol-gel, spin-on-disk, PACVD or CVD methods. Of course, a combination of the methods for different functional layers is possible.
- the at least one functional layer is applied by means of a sol-gel process and baked at temperatures between 300 and 1200 ° C, preferably between 500 and 700 ° C. This process provides high quality coatings and is relatively cheap.
- Production methods which are preferred according to the invention are thus: deposition from the vapor phase by means of PVD and CVD as well as sol-gel or spin-on coating and the thermal conversion of a previously applied metal layer.
- the thermal CVD process is a way of depositing layers with high energy input. Typically, the layer deposition takes place at temperatures between 900 and 1200 ° C. Plasma-assisted CVD processes such as PACVD enable layer deposition at temperatures of 50 to 500 ° C.
- PVD processes for depositing optical layers typically reach temperatures of up to approx. 450 ° C.
- the plasma support or the ion bombardment leads to a compression of the applied layer.
- Another possibility, the generation of coatings with high energy input is the use of a sol-gel process as a coating method.
- the sol-film applied to the substrate is baked in an oven after application and drying, so that the energy input can be realized via the stoving temperature.
- the upper limit of the temperature range when using glassy or glass ceramic substrates is typically around 500 ° C.
- Layer thicknesses should vary, in particular for an optical coating, by less than 1% of the layer thickness. However, with the current PACVD methods, the variations are approximately 30% of the average layer thickness.
- metal of a target is melted by means of an arc, producing a metal vapor which condenses on the colder component surface.
- a metal vapor which condenses on the colder component surface.
- small molten baths are formed on the target on which bubbles can form. If these bubbles burst, droplets form, which are accelerated to the component due to the voltage applied to the component.
- These egg-shaped metal drops are incorporated into the deposited layer. They represent inhomogeneities that affect the functionality of the coating.
- a sample of a polycrystalline, transparent spinel ceramic was coated with titanium by the Arc PVD method and then converted by thermal oxidation to T1O2.
- the PVD coating was applied in 30 min. at a temperature of 500 ° C, in principle, coating temperatures between 50 and 800 ° C are possible, and carried out a pressure of 10 "2 Pa. Die Thermal oxidation takes place under an atmosphere with the mixing ratio of 80% nitrogen and 20% oxygen at temperatures around 1000 ° C and a holding time of two hours. Compared to the maximum possible temperature of glass of about 500 ° C, the temperature could be doubled to 1000 ° C.
- the energy requirement to heat a sample of geometry 90 x 90 x 5 mm with a sample weight of 145 g from room temperature to 500 ° C is 54.9 kJ.
- an energy amount of 100.8 kJ is required for the same sample. This results in an increased energy input of 59.5 kJ compared to the maximum possible energy input in glass.
