Abstract
The present document discloses a glazing in the form of a window glass or vehicle glass which comprises a transparent glass substrate, and a coating, which comprises at least one functional metal Ag alloy coating layer. The alloy coating layer consists essentially of Ag with an alloying agent selected from a group consisting of Mg, Al, Si, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ge, Zr, Nb, Mo, In, Sn, Hf, Ta or W. An alloying agent concentration is 0.15-1.35 at. %, preferably 0.20-1.00 at. % or 0.25-0.80 at. % of the Ag alloy coating layer, the rest being Ag, and the Ag alloy coating layer has a thickness of 5-20 nm, preferably 8-15 nm or more preferably 8-12 nm.
Claims22
Glazing in the form of a window glass or vehicle glass, comprising:
- a transparent glass substrate, and
- a coating, comprising at least one functional metal Ag alloy coating layer,
- wherein the Ag alloy coating layer consists of Ag with an Al alloying agent and inevitable impurities,
- wherein the alloying agent is present in a concentration of 0.29-0.77 at. % of the Ag alloy coating layer, the rest being Ag, and
- wherein the Ag alloy coating layer has a thickness of 5-20 nm.
A method of producing a glazing in the form of window glass or vehicle glass, comprising:
- providing a transparent glass substrate,
- applying, by Physical Vapor Deposition, at least one functional metal Ag alloy coating layer to the substrate, such that
- the Ag alloy coating layer consists of Ag with an Al alloying agent and inevitable impurities,
- wherein the alloying agent is present in a concentration of 0.29-0.77 at. % of the coating layer, the rest being Ag, and
- the Ag alloy coating layer has a thickness of 5-20 nm.
