Scratch resistant coated glass article resistant fluoride-based etchant(s)
View Patent ↗A scratch resistant coated article is provided which is also resistant to attacks by at least some fluoride-based etchant(s) for at least a period of time. In certain example embodiments, an anti-etch layer(s) is provided on the glass substrate in order to protect the glass substrate from attacks by fluoride-based etchant(s). In certain example embodiments, the anti-etch layer(s) is substantially transparent to visible light. In certain embodiments, a DLC layer(s) may be provided over the anti-etch layer. An underlayer may be provided under the anti-etch layer(s) in certain example embodiments.
1. A window on a subway car, train or bus, the window on the subway car, train or bus including a coated article comprising:
a glass substrate;
an anti-etch layer comprising indium oxide directly on and contacting the glass substrate, wherein the anti-etch layer is resistant to at least some fluoride-based glass etchants; and
a layer comprising diamond-like carbon (DLC) provided on the glass substrate over and directly contacting the anti-etch layer comprising indium oxide, so that the window on the subway car, train or bus comprises the layer comprising DLC over and contacting the anti-etch layer comprising indium oxide in order to reduce effects of graffiti on the window of the subway car, train or bus.
2. The window on the subway car, train or bus of claim 1 , wherein the coated article has a visible transmission of from about 10 to 90%.
3. The window on the subway car, train or bus of claim 1 , wherein the anti-etch layer is at least about 2,500 Å thick.
4. The window on the subway car, train or bus of claim 3 , wherein the anti-etch layer is from about 3,000 to 5,000 Å thick.
5. The window on the subway car, train or bus of claim 1 , wherein the glass substrate comprises borosilicate glass.
6. The window on the subway car, train or bus of claim 1 , wherein at least two of said anti-etch layers are provided on the glass substrate.
7. A window on a subway car, train or bus, the window including a coated article comprising:
a glass substrate;
an anti-etch layer comprising indium oxide and/or cerium oxide directly on and contacting the glass substrate, wherein the anti-etch layer is resistant to at least some fluoride-based glass etchants; and
a layer comprising diamond-like carbon (DLC) provided on the glass substrate over and directly contacting the anti-etch layer, so that the window on the subway car, train or bus comprises the layer comprising DLC over and contacting the anti-etch layer in order to reduce effects of graffiti on the window.
8. The window on the subway car, train or bus of claim 7 , wherein the coated article has a visible transmission of from about 10 to 90%.
9. The window on the subway car, train or bus of claim 7 , wherein the anti-etch layer is at least about 2,500 Å thick.
10. A window on a subway car, train or bus, the window including a coated article comprising:
a glass substrate;
an anti-etch layer supported by the glass substrate, wherein the anti-etch layer is resistant to at least some fluoride-based glass etchants; and
wherein the anti-etch layer comprises a fluoride of at least one of MoIn, MoTa, Nb, Ta, In, Ce, Zr and NiCu, so that the window on the subway car, train or bus comprises the anti-etch layer in order to reduce effects of graffiti on the window.
