Definitions
- the glass sheet is preferably soda-lime glass. It is advantageously obtained by floating.
- Other glass compositions are however possible, for example compositions of the borosilicate or aluminosilicate type.
- the glass sheet may be clear glass or tinted glass, preferably tinted glass, for example green, gray or blue.
- the chemical composition of the glass sheet advantageously comprises iron oxide, in a weight content ranging from 0.5 to 2.5%. It can also comprise other coloring agents, such as cobalt oxide, chromium oxide, nickel oxide, erbium oxide, or else selenium.
- the glass sheet preferably has a thickness of between 0.7 and 5 mm, in particular between 1 and 4 mm, or even between 1.5 and 3 mm.
- the glass sheet preferably has a surface area of at least 1 m 2 .
- the sublayer is placed in only part of the enamel area.
- the zone coated with the sublayer represents between 1 and 90%, in particular between 2 and 60%, or even between 3 and 40%, and even between 4 and 10% of the surface of the enameled zone.
- the sub-layer is placed in the whole of the enameled area. It is then a question of avoiding embrittlement throughout the enamelled area.
- the thickness of the sublayer is preferably between 10 nm and 1 ⁇ m.
- the thickness of the sublayer is preferably between 20 nm and 200 nm, in particular between 30 nm and 100 nm.
- the thickness of the sublayer is preferably between 50 nm and 800 nm, in particular between 100 nm and 300 nm.
- the thickness of the undercoat in the final material after firing the enamel.
- the material claimed also covers the intermediate material before firing the enamel.
- the thickness of the sublayer can be greater, in particular between 500 nm and 3 ⁇ m.
- melt layer is understood to mean both the layer before baking and after baking.
- the material therefore comprises above the enamel layer a collecting strip of silver paste in a so-called welding zone in which the collecting strip is intended to be welded, or is welded, to a metal connector, and the sublayer is placed in line with this weld zone, in particular only at the right of this weld zone.
- the silver paste comprises silver particles and a glass frit and is generally deposited by screen printing.
- the metal connector is in particular made of steel containing chromium.
- the solder alloy is in particular based on tin, silver and copper.
- the glazing is preferably a rear window.
- the glazing then generally comprises a single sheet of thermally toughened glass. Alternatively, it may be a laminated glazing, the glass sheet not being thermally toughened but being adhesively bonded to another glass sheet.
- a silica sub-layer 70 nm thick was deposited by cathodic sputtering on a sheet of clear soda-lime glass 3.85 mm thick marketed by the Applicant under the reference Planiclear.
- a layer of black enamel (Ferro 14501) of 25 mpi wet thickness was then deposited by screen printing on the undercoat.
- the thus coated glass sheet was then tempered after heat treatment at 650 ° C for 180 seconds.
- FIG. 1 represents the results of the tests in the form of a graph indicating the probability of failure (noted P) as a function of the stress (noted C) in MPa.
