Definitions
- the present invention relates to glazing comprising a stack of layers of metallic appearance reflecting visible light and capable of withstanding thermal treatments of the annealing, bending, thermal quenching type.
- Such glazing comprises on a glass substrate a coating 10 comprising an essentially metallic layer reflecting a major part of the visible light, most often in silver or alternatively in another metal such as chrome. Most often this reflective layer is encapsulated in the stack by dielectric materials to protect it from corrosion. Glazing coated with such a stack of layers having this fundamental structure are known in different embodiments. In other cases of use, for example for covering walls or facades, for aesthetic reasons, the emphasis here is placed more on the reflective properties of the stack of layers.
- Glazing having a high metallic reflection and a relatively low light transmission are thus very decorative.
- they are often used for cladding walls, facades (as glazing or facade paving) as mirror elements, as semi-transparent mirrors or as decorative glass plates. They can also be provided with an additional decorative impression and are most often used in tempered and/or curved (curved) form. If they are used as monolithic glass panes, the surface layer is exposed without any protection to the atmosphere, so that it must have a particularly high resistance capacity against the atmospheric influences but also sufficient resistance to scratches, essential in particular for cleaning operations.
- the 5 coated glass substrates intended for these applications are conventionally prestressed by thermal tempering, i.e. say heated to a temperature above 500°C, 550°C or even 600°C and then very quickly cooled.
- thermal tempering i.e. say heated to a temperature above 500°C, 550°C or even 600°C and then very quickly cooled.
- the stack of thin reflective layers described above must be able to overcome this thermal stress without damage.
- coated glass glazing must not be disturbed as a result.
- the dielectric base layer consists of a material based on SiO2, Al 2 O 3, SiON, Si 3 N 4 or AlN or a mixture of at least two of these materials.
- the use of a base layer of silicon nitride is to be preferred because it protects the chromium layer better than another layer such as oxide. silicon.
- the upper layer according to this publication can be based on silicon, silicon nitride or aluminum nitride. It is indicated in this publication that the thickness of this layer is between 2 and 20 nm, so as to limit the color in reflection of the glazing, particularly on the coating side. New glazing is now being sought with a light transmission significantly lower than that covered by EP 0962 429, and in particular less than 1%, or even less than 0.5%. To obtain such glazing, the applicant company thickened the chrome layer, based on the stacks described in this publication. Such thickening leads to a drop in light transmission but together with an increase in the visibility of defects such as corrosion points as described subsequently in the 10 examples.
- the invention thus aims to develop glazing having a light reflection RL of the glass greater than 45% and preferably greater than 50% and a light transmission TL less than 1%, and preferably less than 0.5%, and comprising a stack of 15 reflective layers with a metallic appearance, having high resistance to scratching and corrosion and high thermal stability, such that it can withstand heat treatment at a temperature above 500°C, in particular quenching, a bending or other, without the appearance of corrosion points (pinholes) and whose coloring is substantially neutral in reflection on the glass side (a* and b* less than 5 in absolute value and if possible negative in the Lab system) and very little color on the stacking side (in particular a value of b* less than or equal to 6 to avoid too marked yellow coloring), after said heat treatment.

- the layer consists essentially of Ti.
- this layer is at least partially oxidized to the corresponding oxide.
- a layer of Ti is ultimately present in the stack in the form of TiOx, after quenching.
- the glazing according to the invention is constituted by a glass substrate on which the layers of the stack are deposited and are said to be “bombable”, and/or “tempenable”, that is to say that they can undergo such a heat treatment. without significant modification of their appearance (particularly in terms of corrosion and colorimetry).
- the stacks of layers according to the invention are advantageously deposited on the glass substrates following known reactive cathode sputtering processes assisted by a magnetic field in industrial continuous coating installations.
- the coated glazing can then be subjected to a usual tempering process, without the stack of layers significantly losing its desired optical and aesthetic properties, in particular its colors in reflection.
- an additional layer can be applied, for example a layer of continuous color in particular opaque, on the coated side, possibly for aesthetic purposes or to manufacture opaque glazing of the type lightens.
- This layer can also be made of paint or enamel, obtained by baking an enamelling composition in a known manner.
- the cooking operation can advantageously be linked to the annealing, bending or quenching operation of the glass substrate carrying the stack. The two operations can thus be concomitant.
- the conditions for depositing the stack are as follows: On an industrial vacuum coating installation, 4 mm thick Planiclear TM clear float glass substrates are coated using a conventional cathode sputtering process assisted by a magnetic field, to obtain the following stack of layers: Glass - 15 nm Si3N4 - 55 nm Cr - 3 nm Si3N4 - 3 nm Ti
- the SiO2 layer is sputtered in DMS mode (Dual-Magnetron-Sputter mode), with two cathodes and an alternating current under a reactive atmosphere from a Si target with a working gas composed of Ar/O2, and the Si3N4 layer under a reactive atmosphere from a Si target with a working gas composed of Ar/N2, according to well-known techniques in the domain.
- Example 2 (comparative) In this example, we increased the thickness of the silicon nitride layer deposited above the chrome layer: We proceed in the same way as for example 1 to obtain the glazing following: Glass - 22 nm Si3N4 - 55 nm Cr - 23 nm Si3N4 – 2 nm of Ti Example 3 (according to the invention) In this example, we proceed in the same way as for example 1 to obtain the glazing following: Glass - 22 nm SiO2 - 55 nm Cr - 23 nm Si3N4 - 2 nm of Ti Example 4 (comparative) In this example, we proceed in the same way as for example 1 to obtain the following glazing: Glass - 22 nm SiO 2 - 55 nm Cr - 23 nm Si 3N4 - 2 nm of Ti Example 4 (comparative) In this example, we proceed in the same way as for example 1 to obtain the following glazing: Glass - 22 nm SiO 2 - 55 nm Cr
- Optical quality The measurement of the transmission of the layer system in the visible spectral zone TL, of the reflection in the spectral zone visible RL (according to illuminant D65) according to standard ISO9050 (2003).
- the coordinates a* and b* are determined in the CIELAB colorimeter system (L, a*, b*).
- - Mechanical resistance the scratch resistance of the coatings was measured using a SCRATCH HARDNESS TESTER 413 device supplied by the company Erichsen according to the following protocol: The sample is mounted on a rotating table (number of revolutions in the standard version: 5 min -1 ).
- the test tool is attached to a load arm with an adjustable weight that allows the pressure of the tool to be adjusted to the sample (load range 0 to 10 N).
- the resistance of the sample to this effect is assessed visually using the scratch track.
- the sample is considered suitable for marketing if there is no no visible scratches with a load of 1 N and low visibility of scratches at 3 and 5N.
- - Quenching corrosion test the number of corrosion points is observed visually after quenching. We define 3 levels 5 of occurrence: ++: very numerous points of corrosion (pinholes) +: a few visible points of corrosion 0: no visible points of corrosion 10
- the results of the tests carried out to evaluate the properties of the layers are collected in the following Table I, in which the results of the tests on the coated glazing after the tempering treatment are reported.
- Comparative Example 2 further shows that a thicker underlayer based on silicon nitride leads to a marked and undesirable yellow appearance of the glazing in reflection on the stacking side (value of b* much greater than 6).
- Comparative Examples 4 and 5 show the importance of selecting the thickness of the layer between 1 and 3 nm: thus a thickness of 3 nm leads to an undesirable marked yellow appearance of the glazing in reflection on the stacking side whereas a layer of 1 nm does not provide sufficient mechanical strength of the stack.
- Comparison of comparative example 7 with example 3 according to the invention also shows that an additional metallic layer of Ti above the layer of silicon nitride in the stack only very slightly modifies the value b * in reflection on the stacking side, but only if its thickness does not reach 3 nanometers (comparative example 4).
- Comparative Example 6 shows that too much thickness of the silicon nitride layer above the reflective chromium layer of chromium also leads to an undesirable marked yellow appearance of the glazing in reflection on the stacking side (b* much higher to 6).
- the substrate provided with the stack of layers is preferably made of glass, and can be used as monolithic or incorporated glazing in a laminated glazing or multiple insulating glazing structure. It can remain transparent or be opaque, and be continuous or present patterns. 5
